I had the same message on my TP765L. I wrote a kernel patch which
tweaks DMA port detection to use a hardcoded address, which gives me
DMA transfers for the hard disk. I will search for it on my hard drive
and send it to you.

Do you use the kernel PCMCIA driver? On my 765L, this won't work with
cardbus, since the cardbus bridge uses ISA IRQs instead of PCI IRQs (at
least the author of pcmcia-cs, David Hinds, wrote this to me). The
solution was to PCMCIA support in the kernel and use the driver from
the pcmcia-cs package.
