No worries and thanks. By the way, you mentioned something about other problems
with ide-tape. FWIW, it seems you're its only user and we were about to kill it
but decided not to yet and did the whole cleanup kinda only by compile-testing
since almost no one (well, except you :)) has the hardware. So, feel free to
send me any dmesg/debug/error messages you get and I'll look into them. Also,
set IDETAPE_DEBUG_LOG to 1 before compiling for full debug info.

Thanks.
