Attached are lspci and dmesg output, _alone = old kernel on laptop only,
and _dock_fix = patched kernel in base station.

The patch allows booting while docked, and I tested a CD-ROM in the base
station - it works!

Other /proc files seem ok, except /proc/ide/triflex, which spews
garbage. ld-linux.so was in the output, so it seems to be just
returning random memory contents. Smells like a pointer problem.

But this is great progress! Thanks so much for your efforts!
