With cvsbk rev 423b66b6oJOGN68OhmSrBFxxLOtIEA (rsynced Monday, it claims
to be "2.6.12-rc1"), the situation is much improved. The AlpsPS/2
driver recognizes the trackpad, tracking speed is back to normal, and
tapping is turned on by default. (Drat, now I need to figure out how to
turn that off again.)

The kernel output is a bit odd, though:

[ 1200.254707] Adding 987988k swap on /dev/hda3. Priority:-1 extents:1

[ 1206.183165] kjournald starting. Commit interval 5 seconds

Note how the "Enabling hardware tapping" message is several lines
earlier than it seems it should be... I don't think I'm supposed to be
tapping on my SCSI hardware.

... ah, I think I'm missing the "ALPS GlidePoint detected" message which
I used to get. Without it, the "Enabling hardware tapping" message is a
bit opaque.

Other than that, I have no complaints about the trackpad.

Thanks for the ping.
