Now when I start an autoyast installation on an IDE based  system this
works fine. But if I do the same on a SATA system the installation fails
when creating the partioning plan because of the fact that there is no hda
device but instead a sda. Actually I do not care about this failure since I
would like to do this manually, but I cannot because of this error the
complete installtion is stopped and I do not get to the point in yast where
I could correct the partitioning and other installation parameters.
Two ways. Either use rules, and create two partitioning sections. Something 
like, 

	<rule>
    	<disksize>
			<match>/dev/hda 10000</match>
			<match_type>greater</match_type>
		</disksize>
		<result>
			<profile>rule-has_ide_partitions.xml</profile>
			<continue config:type="boolean">true</continue>
		</result>
	</rule>
	<rule>
    	<disksize>
			<match>/dev/sda 10000</match>
			<match_type>greater</match_type>
		</disksize>
		<result>
			<profile>rule-has_sata_partitions.xml</profile>
			<continue config:type="boolean">true</continue>
		</result>
	</rule>

See the rules section in the docs for more details, 

Or, use a pre script to re-write your config. (this one does several mods to 
the file)
[warning, ugly, inelegant perl follows, there's much better ways to write 
this]

<scripts>
<pre-scripts config:type="list">
        <script>
          <filename>mod-configfile</filename>
          <interpreter>perl</interpreter>
          <location></location>

my $infile = "/tmp/profile/autoinst.xml";
my $outfile = "/tmp/profile/modified.xml";

my $domain;
my $disk="";

print "test script to modify the autoyast config file\n";

#read the command line;
open CMD, "/proc/cmdline" or die "can't open cmdline";
my $line = <CMD>;
my @line = split ' ', $line;
my %line;
foreach (@line) {

  $line{$1} = $2;
  print "$1 = $2\n";
}

#read resolv.conf and find the domain.
open RES, $resolv ;
while (<RES>) {
  next unless /^search/;
  /^search (.*.novell.com)/;
   $domain=$1;
}
#a domain specified on the command line will overwrite that in the resolv.conf
if ($line{domain}) {
  $domain=$line{domain} 
};

#see if we have scsi or IDE disks. If we have both, assume IDE is bood disk. 
if (`/sbin/fdisk -l |grep -c sda` > 0) { $disk="sda" };
if (`/sbin/fdisk -l |grep -c hda` > 0) { $disk="hda" };

#if hostname not set, set a default

if (! $line{host}) {
  $line{host} = "nohostname";
}

open IN, $infile;
open OUT, ">$outfile";
while (<IN>) {
  if ( /<domain>(.*)<\/domain>/ ) {
  	print "found it\n$_\n";
	print OUT "<domain>$domain</domain>\n";
  }

A second question is if there is a way to pause autoyast after the initial
reboot, when in a standard yast installation the user is asked to do the
printer, network, soundcard etc configuration. It would be nice (but not
vital) if I could change things manually at this point too in the standard
yast way. Any way to do this?
That's covered in the docs I think. section 4.1, page 27 of 
file:///usr/share/doc/packages/autoyast2/autoyast.pdf

Change starting from SUSE Linux 10.1/SLES10

[snip]
Since now you can use the second_stage property, which can turn off autoyast 
after the
first reboot. So the complete second stage is a manual installation (default 
is true,
which means that autoyast is doing a complete installation).
