hmm, usually the windoof user get the hardware, linux
refuses to run stable on, not the other way round ...
this ist mostly because windoof crashes anyway, so adding
some crash probability almost always goes unnoticed ;)

linux tends to push hardware much further than windoof, so
often bad hw designs will result in malfunction ...

to take a system down, one kernel line is enough,
but as it seems relatively stable (I'm speaking of 2.4.22
and ctx17a) for others, I tend to believe its something
in your hw/config/setup which triggers something in the
kernel (or hardware), unless proven otherwise ...
