This is definitely true.  Under Linux, my 2GB Toshiba Hard Disk does not
work.  I haven't looked at how sa1101_jornada820.c handles setting power,
but the card refuses to even ident under Linux, and works fine in Windows
CE and my yenta socket.  What registers I should be looking at in Windows
CE, to see how the power is set?  The card doesn't work/powerup until I
say yes to the "Do you want to use this PC card on battery power?"

Such as USB, VGA, X, userspace, etc.  I will endeavour to get USB working
in the next day or two.

This is good news.

Have you scanned the 32MB module and given a copy to the list?  It would
be nice to create a schematic and PCB for those of us without 32MB of
