I found the reference in the meantime, it is openSUSE 10.3 release notes. It says:
"libata uses /dev/sda for the first harddisk instead of /dev/hda. Disks with more than 15 partitions are not handled automatically right now. You can disable libata support by booting with the following kernel parameter: hwprobe=-modules.pata"
Note that libata is generally the superior performer, performance not exclusively meaning I/O speed. At some point prior to 10.3 release at least the parameter was brokenmodules=<actual libata driver>, e.g. brokenmodules=ata_piix for Intel.
I checked openSUSE 11.0, 11.1 and 11.2 documentation: In 11.0 and 11.1 the same kernel parameter is used as in 10.3. In 11.2 no kernel parameter required. (At least the doc [Reference guide] does not mention it.)
That part of the guide got an update it needed for 11.2. AFAIR, it's still possible to use IDE instead of libata in 11.2, but I don't think any compelling reasons to remain. For some multidisk users I suppose there may be some benefit to being able to stick to the legacy hda, hdb, hdc & hdd device names.
11.2 Reference guide says (Chapter 2.1.1): "The maximumnumber of logical partitions is 15 on SCSI, SATA, and Firewire disks and 63 on (E)IDE disks."
This part of the doc didn't get the update it needed. 11.2 has a 2.6.31 kernel. The post 11.1/2.6.27 kernels lifted the libata (necessary for SCSI, SATA, Firewire) restriction from 15 to (AFAIK) 63. Don't forget though in case you care that 11.2 has no supported KDE 3. -- "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
