I cannot see an actual problem here. Therefore closing the report. The installation system can be booted into safe mode on machines where the full feature set creates problems. ACPI is not really required for an installation.
I don't know which `unsupported kernel' are you talking about. All sources for our packages are available.

Reopening.

Thomas: This kernel you released on your FTP space: Please point out the sources or devel headers and comment about the nature of this kernel (What did you change/add here and what about it is unofficial? Can this kernel be redistributed without concern?).

I already answered.
The patch is just reverting the result= in drivers/acpi/pci_link.c
Unmodified:
/* Query _CRS, set link->irq.active */
        result = acpi_pci_link_get_current(link);
        if (result) {
                goto end;
        }

Modified:
/* Query _CRS, set link->irq.active */
        acpi_pci_link_get_current(link);
        if (result) {
                goto end;
        }

Sorry for not patching ...
The changes are in kernel CVS and he can take kernel binaries/sources from ftp.suse.de/pub/people/mantel/kotd/10.0-*/...
