Parallel Port support on Indy?

Hi there;

  I've recently acquired an Indy, and I'd like to use it as my closet
firewall/webserver/printer box. I've been able to install debian/woody
without event, and the linux_2_4 tag from sgi's cvs compiles fine,
giving me OSS sound support with the HAL2 and enabling the Vino video
system. X came working out of the box...

The only thing I *can't* do with the Indy is use the parallel port,
which, in my case, is the most important thing... As far as I can tell
from reading around, the Indy supports a standard SPP parallel port
(plus a bunch of extra modes that haven't been implemented in linux,
afaict), but has a different base i/o address in addition to having the
data and control addresses at different offsets. I tried playing around
with the constants in [header file that controls that stuff in
include/linux], and managed to get the parport_pc module to stop causing
a [non-fatal] kernel oops. Now it just says something is wrong. ;-)

I would like to pursue fixing this, but being a student and not having
any experience playing with low-level hardware or kernel hacking are
conspiring against me. Is getting parport support on the Indy a major
undertaking, or are there just a few tweaks that need to be made to
existing drivers?

Any help on this would be most appreciated.
