I _believe_ it is the old version 2.5 source (by 3.0, support seems to have
been dropped)...

Unfortunately, the chipset and driver support is SO old that it wouldn't
even support the machine I have, so since I'd have to add device drivers
anyway, I'll probably just add support to OSKit for Alpha for select devices
that are common and generic to both x86 and alpha platforms (i.e., VGA,
PS/2, COM ports, etc.)...

I've got both FreeBSD and Linux installed on my machine, so I'll probably
grep from both of them...
