Correct. I guess, that I need AIC7XXX support as well
(I've attached both .configs).

The vanilla kernel boots without initrd and detects the
ServeRAID controller "without" problems (ok - obviously
2.6.12s ServeRAID driver is too new):

ips 0000:02:05.0: Warning ! ! ! ServeRAID Version Mismatch
ips 0000:02:05.0: Bios = 7.00.14, Firmware = 7.00.14, Device Driver = 7.10.18
ips 0000:02:05.0: These levels should match to avoid possible compatibility 
problems.

I checked the troubleshooting tip

When running the multiple processor kernel, Linux has a
problem accessing controllers that are assigned IRQ 9 by the
system BIOS. To correct this problem, enter the system BIOS
and change the IRQ assigned to each controller.
     
but 

mehl:~# cat /proc/interrupts

Generic SCSI support is enabled in both kernels, too.

Further hints?
