I think it is an aic7899 in the Dell 6450 server I had available
a short while ago, and it seemed to just work right out of the
box with 1.5 and -current code, although only in 80MB/s mode, it
would seem.

The relevant autoconf output was

ahc1 at pci0 dev 5 function 0
OptionMode =3D 3
ahc1: interrupting at irq 11
ahc1: aic7899 Wide Channel A, SCSI Id=3D7, 16/255 SCBs
scsibus0 at ahc1 channel 0: 16 targets, 8 luns per target
ahc2 at pci0 dev 5 function 1
OptionMode =3D 3
ahc2: interrupting at irq 10
ahc2: aic7899 Wide Channel B, SCSI Id=3D7, 16/255 SCBs
scsibus1 at ahc2 channel 0: 16 targets, 8 luns per target
