I tried that.  It worked.  Thanks a lot!  Looks like the fe0 driver was
the 
one messing it up for my ep0.  Now back to the install.

Another weird thing: as you could see in the boot dump, a Seagate UDMA2
drive
has been detected.  After sysinstall starts, I see the following
messages
on vty1:

ad0: ad_timeout: lost disk contact - resetting
ata0: resetting devices .. ata0-master: timeout waiting for command=ef
s=fc e=00
ata0-master: timeout waiting to give command=ef s=fc e=00
ata0-master: timeout waiting to give command=ef s=fc e=00
ad0: ad_timeout: lost disk contact - resetting
ata0: resetting devices .. ata0-master: timeout waiting for command=ef

ata0-master: timeout waiting to give command=ef s=fc e=00

ad0: ad_timeout: lost disk contact - resetting
ata0-master: timeout waiting for command=ef s=fc e=00
ad0: ad_timeout: trying fallback to PIO mode
ata0: resetting devices .. done

and the setup continues as if nothing has happened.  The drive is
configured as PIO mode 4 in the BIOS (the BIOS does not support UDMA,
the chipset apparently does).  Any pointers?
