1.0.0pre1: au88x0 driver locks up kernel

[Carolyn and Eric Hathaway <hathaway@uplink.net>]

I'm running RedHat 7.3 (RH kernel 2.4.20-20.7, gcc 2.96-113), and have a
generic Aureal Vortex 1 card (au8820 chipset).  Compiling and installing
the 1.0.0pre1 ALSA driver works fine, but if I do a 'modprobe
snd-au8820', the computer locks up instantly (can't even ssh in from
another computer).

Going back through recent CVS commits, I found that the problem is
caused by the changes described in the following alsa-cvslog message:

http://sourceforge.net/mailarchive/message.php?msg_id=6552838

Specifically, the problem is caused by the changes Takashi made to
au88x0.h and au88x0.c to eliminate calls to pci_request_regions() and
pci_release_regions().  If I revert those two files to their previous
versions, the driver compiles and works fine.  I'm not an ALSA driver
guru, but I didn't see anything immediately wrong with the changes
introduced by the above CVS commit that would cause such a drastic
kernel error.  Perhaps someone more familiar with the code in question 
could take another look at those changes?
