2.6.10 kernel:

Machine with driver and without card works well.

Machine with card inserted and module airo_cs.ko rename to _airo_cs.ko works 
too (obviously the card does not work without driver).

Machine with card inserted and module in place this time showed
a strange behavior. This time it repeatedly printed error messages from ide bus
that the hda disk did not work anymore for about 2-3 minutes (dma failed).

Then the machine booted normally but without detecting the card.
Since the machine was running this time, I was able to save
dmesg output:

cs: memory probe 0x60000000-0x60ffffff: clean.
airo:  Probing for PCI adapters
airo:  Finished probing for PCI adapters
Uhhuh. NMI received. Dazed and confused, but trying to continue
You probably have a hardware problem with your RAM chips
airo: Max tries exceeded when issueing command
airo: MAC could not be enabled
airo_cs: RequestConfiguration: Operation succeeded
hda: dma_timer_expiry: dma status == 0x61
hda: DMA timeout error
hda: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }

ide: failed opcode was: unknown
hda: dma_timer_expiry: dma status == 0x61
hda: DMA timeout error
hda: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest }

ide: failed opcode was: unknown
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

... repeated several times ...

ide: failed opcode was: unknown
hda: drive not ready for command
ide0: reset: success


Then the machine was booting. Maybe it's a problem with interrupts.
