   You're right. I took a brief look at the source, noted it was a
standalone C program (no kernel patches) and I wasn't thinking.

   Actually, it seems the Zaurus driver is the bt950_cs after
all. Only had the thing two weeks and I'm still trying to get the hang
of it: silly me assumed that a 'locate bt950' command would work.

   The goal was, now that I think about it, to run the BT2000 on my
i386 laptop, where I can get at it lots easier and try to troubleshoot
the slow transfer rate on pand problem. I've tried bluetooth transfers
on tha laptop with a USB Tecom BT3030 (same as the server end) and got
a rate of 55k - 60k bytes/sec, which is much nearer to what I'd
expect. I thought I'd try the BT2000 on the laptop and see what
happens, trying to decide whether it's a driver problem or one related
to the Zaurus. That's when I found that the current kernel on that
machine (2.4.22) doesn't have a bt950 driver.

   Sorry if I confused you.

   I think I just found the problem. I was trying to compile it on my
desktop, which I use to generate kernels for all my machines. Seems
that /usr/src/linux was symlinked to the 2.6.0 source. I just tried it
with the 2.4.22 source and it compiled ok (with some grumbling about
type-punned pointers and strict aliasing rules, whatever they are). I
will transfer it to my laptop and see what happens. Doesn't look like
it'll compile under 2.6.0, though.

   Thanks for your help.
