The OSS driver that you selected has not been converted to use the new pci API
I'm not sure if it will ever be updated though, since alsa is now part of 2.5
try to use the alsa drivers instead. If you read this
virt_to_bus_not_defined_use_pci_map carefully yo will see that it says
virt_to_bus not defined use pci_map nice way to get people to fix the old drivers
;)

I really wish the OSS drivers would be fixed.  They worked perfectly with my
Crystal SoundFusion card, but the ALSA drivers are very unreliable with it.
Sometimes they work, sometimes they don't.  (One day a couple of weeks ago I
rebooted about ten times, and the sound worked consistently *on alternate boots*
(that is, it didn't work after the first boot, worked on the second boot, didn't
work on the third, worked on the fourth, etc.).  The next day it worked on every
boot.  Since then it works sometimes, and sometimes doesn't, with no discernible
pattern.  Even when it's working, it works sporadically -- some sound effects in
Gnome work, others don't, then a few minutes later they all work again;
RealPlayer works OK until I open a new window, then the sound cuts out and won't
start again until I restart RealPlayer; and so forth.  The OSS drivers don't
give me any of these problems.

In the longer term its more productive to fix the ALSA drivers and import
any fixups they need. 2.5 is about the longer term maintainability of audio

Re: 2.5.7 make modules_install error (oss)

[J Sloan]

Agreed, the oss drivers should _at least_
be maintained as an alternative, e.g. for
those of us who want reliable sound with
*low latency*

<explanation>
I haven't checked lately, but not too long
ago the alsa drivers were found to be one
of the worst sources of latency in the kernel.

Not really. Well not unless you wish to volunteer.

So fix it. On an SMP box the mess the oss drivers make is very visible
because its all running under lock_kernel

Well, if I feel the pain, the motivation is there...

If the alsa drivers do not seem a viable choice,
then I'll certainly volunteer to maintain the oss
stuff that I find neccessary (mostly a collection
of sb cards) -

Of course, there is always the possibility that
alsa will turn out right in the end...

You should really take care about your words. You've not written any
technical reason to say these sentences. We are not aware about any
problems against low-latency. Sure, OSS API emulation is only emulation,
so there is additional layer which can be a bit slower than simplified
native OSS drivers, but using ALSA API, we get really serious latencies
even for multichannel hardware.

I propose to join to our efford and fix (or at least - point to) problems 
(if any) in ALSA drivers. Thanks.

Fair enough - I don't see any technical
reasons why alsa *couldn't* perform as
well, latency wise, as oss.

Some folks on this list had been doing latency
profiling on their kernels during the past year
(sorry, I don't remember the exact dates) and
surprisingly the alsa driver was showing up
as one of the top sources of latency - IIRC one
possible explanation was "in-kernel mixing".

Thanks for the feedback, I'll have to do some
testing of my own and see what the situation
is at this point - I'd be very happy to learn that
my concerns are outdated and already resolved.
