Since this is Sarge, is it safe to assume that this is all being done manually, or there some HAL or other auto-mount daemon involved? Assuming manual: (never having used an amd I'd be lost) You need to see the syslog at the same time as the unmount happens. Whenever I'm diagnosing a system freeze like this, I stop X to to take a big variable out of the picture. That leaves you at a VT. Ideally, you'd set up a serial console to log everything going to the console, and using sysctl.conf, allow all kernel messages to be printed on the console. Then from a VT, issue the umount command (of course ensuring that the stick is free) and watch the console. If you can't hook up a serial console, I'd try using either 'at' or even sleep 1m; umount [stick] on one VT while you switch to the VT running tail -f /var/log/syslog and watch what happens. I didn't get anything USB until after I was running Etch so I don't know how well Sarge handled things like USB sticks. Are modules being loaded or unloaded properly? Good luck.
