G4 Dual 1 Kernel Panics

Hello,
The people known as the Apple Geniuses at my local Apple store were not able to fix my G4 Dual 1Ghz tower. After insisting it was probably the logic board, they replaced it and then (at no further cost to me) allegedly swapped out the processors too. They were happy to keep the money, but then offered me almost the equivalent $ off a new G5 rather than figuring out why my G4 now kernel panics constantly. They eventually changed the hard drive, tested the RAM and tried the machine with a subsitute video card. Still a ghost in the machine. Does this panic log look familiar to anyone?
Thanks!

Got any SCSI cards in there, like an older Adaptec SCSI card?

One of my older machines consistently panics when trying to boot 10.4.4, but does not under 10.4.3, so that's where it's staying for the time being -- and my panic log looks similar to that, referencing the IOSCSIArchitecture thing as well (it's an older 7600 that has on-board SCSI).
