The uvisor driver fails to recognize the Palm z22,
failing with a TIMEOUT error.
The following patch allows the ucom0 device to be initiated.
This is only a hack, since it involves removal of error checking,
but it can be made to be conditional to whether or not this particular
device is attached.
After I made these changes, I was able to sync the device.

(Patch Attached)

Regards,
Jeff Bedard
