Currently, ahc* at eisa? slot ? _should_ work for 284x controllers 
_providing_ an EISA signature appears in the BIOS.  Otherwise, the EISA 
bus is never probed.

As for ahc at isa, that front-end went away with the mass-update of the 
ahc driver a month-ish or so (or more?) ago.  The lack of said front-end 
is _definitely_ a bug.

I just sent off the front-end I wrote for ahc_isa yesterday to Michael 
and Noriyuki.  Hopefully, they can get is tested and put into the tree in 
a reasonable amount of time.  (I can't test it, so I don't feel 
comfortable committing it myself.)

Yes, that's true, however my extent code (and thus, the i386 i/o port 
accounting code built in to bus_io_{,un}map()) only exists in the 
post-1.2 sources.  IMO, it should be pulled up into the release branch, 
since leaving it out means that a large number of users could be left out 
in the code (for want of a SCSI driver).  I'll discuss this with the 
release engineer early next week.

Actually, I pretty much stole the EISA front-end outright, stole some of 
the EISA bus code, and then glued it together.  So, the offset is dealt 
with within the driver.  This is to make it easier to read the ID string 
off the card...

ahc0	at isa? port ? irq ?

or

ahc0	at isa? port 0x1000 irq ?

If the ahc_isa front-end is committed, I want to see the handling of the 
284x taken out of ahc_eisa.  However, I want to see the eisadevs entry 
(for EISA_PRODUCT_ADP7756 and EISA_PRODUCT_7757) remain.  They should be 
denoted as VLbus devices in eisadevs (a comment explaining why they're 
there should suffice).
