 he he - it _should_ be fine, as long as there's no GPIOs being pulled
high/low that do weird stuff.  for example, if you look at the
/drivers kernel modules, you'll see that one of them is for a 3G PCI-e
modem.  when i modprobe'd that module, the kernel logs said "switching
on {modem} blah blah".  that tends to suggest that there's some GPIO
being pulled high or low.

 now, you could write a GPIO read/write program (we did this for the
HTC PXA27x-based devices) or maybe one already exists, so you could do
a "watch" on the GPIOs.

 it's probably a good idea to do that anyway, find out what the
existing / running status is of all the GPIO lines, then make sure
that nothing in the 2.6.33 kernel does anything different.
