I just received the documention for the IDE conrollers
in may older Toshiba notebooks. These controllers are
capable of DMA, but at the moment do not have it
implemented. I know nothing about programming IDE
drivers, so if anyone is interested in developing
these drivers shoot me an email and I can send you the
docs and help with testing (I have several notebooks
to test on). I'd like to get into it myself, but just
don't have the time.

If they follow the standard model you should actully have very little
code to write.

Heh. "No time." Sounds familiar. :)
I don't have the knoff-hoff (know-how) either, but I'd like
to know what models you have info on. I'd be very interested
in any documentation you might have on the Satellite 1605CDS.
At the very least, I like to collect info so that it's available
later on.
I have DMA enabled on my Satellite 1605CDS, but only via a hack.
If I enable ALi 15xx support in the kernel, I find that I can't
suspend my laptop to disk (it hands off to BIOS well, but then
BIOS freezes when it starts to save the "Extended" memory.)
So, what I do is build an ALi-enabled kernel, then reboot to
a non-ALi-enabled kernel. For some reason, it saves this
DMA-enabled info between soft reboots. So, since it's Linux
and I essentially never have to hard-reboot (or even give it
the 3-finger salute) this works fairly well. It's only when
it's actually been shut off or hard rebooted (via the switch)
that DMA gets disabled again.
I'd like to fix the ALi support so I can suspend to disk, but I
don't know where to begin. I don't have the specs.
Where did you get this info? I'd be very curious what else we
can get out.

I'll try and take a look at the code in the kernel
this weekend if I get a chance, however, This is not a
PCI IDE controller (at least it doesn't show up with
lspci). I don't know if that makes a difference or
not.

Sure send the docs over!

That might make it a bit harder, it depends on the general behaviour. If
its bus mastering and follows the standard behaviour you have to provide
the chipset setup and tuning - which is normally "load xyz registers
with abc value for each mode"
Take a look at the serverworks driver
