After supping -current on June 13 and building a kernel with

options PCIIDE_ACARD_ENABLE

in the config, I just completed upgrading the machine from 1.5 to -current
from a source tree on a drive on the IDE card.  (Thanks to Xavier Humbert
for the instructions posted to this list recently!  They surely saved me
much grief.)  'make build' completed successfully in about 7 hours.

Transfer rates aren't quite what I was expecting.  Using a pretty
brain-damaged throughput test (running 'iostat -w 1' in one window and 'cat
/dev/zero >foo' or 'cat foo >/dev/null' in another), I see write rates
approaching 6M/sec and read rates approaching 9M/sec on a relatively modern
20G WDC drive.  I'm sure I've seen better throughput with this drive in
another machine.

The machine is a 7500 with a 300 MHz G3 upgrade.  dmesg output is attached
below.

I see from the CVS logs that the ACARD support in the pciide driver is
disabled in GENERIC because someone was having trouble with it on macppc.
Does my datapoint mean that these problems might have gone away?

BTW, this machine isn't booting from the IDE drive -- there's still a SCSI
drive on mesh0 for boot & root.  (Before the upgrade I had the IDE card
sorta-kinda working with a hacked 1.5 kernel that timed out several times
and fell back to polled I/O mode, but I wasn't about to root on _that_...)
