Hi.

This patch (against arjanv's latest kernel, but should apply to 
2.6.8-rc) is still a little messy and NOT ready to go into the mainline 
kernel... Luben hasn't seen it yet (Hi Luben!), so the usual disclaimers 
apply. But it's time to get some more eyes on it. The good news is it 
works, the bad news is there is no support for error recovery during 
those few seconds when the bus is setttling and hard disk is powering up 
after a resume. (Need suggestions on how best to attack that part, I 
really don't know anything about SCSI...) It works, after a few 
residuals if your filesystems are mounted read-only, however. If you are 
mounted read-write then you will get aborted commands, ext3 will 
complain, and remount your fs read-only until you reboot. To avoid this, 
remount read-only, suspend/resume, then remount read-write manually 
after everything starts working.

One other thing that needs outside eyes to look at is the additional 
call to ahc_pci_config(), from ahc_pci_resume(). It might do some 
redundant initializations, I'm not really sure what is needed and did 
not want to disturb the init order for the normal boot sequence, so I 
just if'd out the stuff that seemed irrelevant.
