nice! thanks! I needed this, but didn't have the proper info to write
the code myself.
I noticed one problem though. It is explained below.
Note: I removed lots of stuff from the original article, just saving
enough context so one can repair.

This line should not be here! remove it.

You'll need a line
Xfs/table.c
here. This is a patch in this file. 
(By the way: patch crashed on this point on an uncorrected file)

What I missed after having this installed was a program to set the minix
clock. I changed megartc.c to cope with both the mega and the bms clock.
However, since I do not own a mega, and my BMS clock shows sometimes
weird behaviour (I think it needs a new power pill), I am looking for
one or a few persons who will test my changes.
Both one or two mega and BMS testers are needed.

Any volunteers??
