Re lpt, I have T41p and in its BIOS the lpt is configured at 0x3bc,
irq 7.  Our GENERIC (and other configs) have lpt2 at that address, but
that line doesn't specify irq, so you end up with the polled mode.
Just Comment out the standard set of lpt attachments and add instead:

    lpt0 at isa? port 0x3bc irq 7

Don't know about the com port (T41p doesn't have DB9 connector), but
check the BIOS settings too.

Or may be try a pnpbios enabled kernel.
