Looks like I've got a similar problem only its aic7880/wide

I've got a Dell optiplex 450 with an Adaptec 2940uw controller which can 
boot but can't "mountroot".

A kernel from last week can see the aic7880/wide but a kernel from the past
couple days cannot.

OK dmesg:

FreeBSD 5.0-CURRENT #10: Mon Mar 12 12:17:02 CST 2001
pcib0: <Intel 82443BX (440 BX) host to PCI bridge> at pcibus 0 on motherboard

0xfafff000-0xfaffffff irq 14 at device 10.0 on pci2
aic7880: Wide Channel A, SCSI Id=7, 16/255 SCBs

Bad dmesg: same thing but:

"ahc0 Platform free" instead of aic7880 line.

Here is pciconf -l
