lestat (thorpej) /work/clean-current/src/sys/dev/isa 450% ll aha2*

Here's a code snippet:

aic7770_sig valid_ids[] = {
  /* Entries of other tested adaptors should be added here */
  { AHC_274,      0x70 }, /*aic7770 on Motherboard*/
  { AHC_274,      0x71 }, /*274x*/
  { AHC_284,      0x56 }, /*284x, BIOS enabled*/
  { AHC_284,      0x57 }  /*284x, BIOS disabled*/
};      

The driver is "ahe":

ahe0    at isa? port 0x1c00 irq ?       # Adaptec 284x SCSI controllers
scsibus* at ahe?

Maybe I should change the comment to # Adaptec 2[78]4x SCSI controllers

There was a permissions botch when I committed the driver, but I've fixed 
it.  Let me know if you have problems.
