i try it - all work fine. i don't test palm records over 64kb or dlp
packets over 64 kb, i test transfer via usb with low-level packet size
over 64b (may be kernel split usb transfers to 64 bytes-blocks - but
why speed increase?). 

ps: what about dlp-packets over 64kb? how can i test it with coldsync?
