It means your kernel has found the same bt0 device twice, once in isa
compatability mode and once on pci. Theres only one actual card, so
"unit number (1) too high" ...

Yes, this is what you must do.
Its slower because you are using your card in isa compatability mode, not
full speed pci.

In your kernel config file (there is information about configuring and
rebuilding your kernel in the FAQ) the line for bt0, change where it says
'isa' to 'pci' and rebuild it .... Its _much_ faster after you do.

From 2.2.1 GENERIC kernel we have:
controller	bt0	at isa? port "IO_BT0" bio irq ? vector bt_isa_intr

You want:
controller	bt0	at pci? port "IO_BT0" bio irq ? vector bt_isa_intr
