autoyast - systems with 128mb and large rpms

Hi, I have noticed that on systems with 128mb of memory, autoyast installation will not be able to handle large RPMS, i.e. Openoffice (50mb+). Performing an ftp install on suse9 using autoyast with a system of 128mb internal memory, the 64mb of ramdisk is really not enough. It will fail when it tries to download the OpenOffice rpm. Fails with unable to write to media error(The same install on the same machine, but with 256mb of internal memory works). Is there a way around this, apart from adding more memory to the machines? I looked into pre-script, but since filesystems get created after pre-script, this seems pointless. -- grant williamson
