SCSI AM53C974 driver missing in 2.6.0?

SCSI AM53C974 driver missing in 2.6.0?

[Ralf Hildebrandt]

% lspci -v
00:0b.0 SCSI storage controller: Advanced Micro Devices [AMD] 53c974 [PCscsi] (rev 10)
        Flags: bus master, stepping, medium devsel, latency 70, IRQ 10

in 2.4.x we've been using 
CONFIG_SCSI_AM53C974=m

2.6.0 doesn't seem to have any support for that specific SCSI
controller. What now? Aternatives?

Kurt Garloff <garloff@suse.de>
and Guennadi Liakhovetski <g.liakhovetski@gmx.de>
have made some recent patches for this driver.
It was discussed on the linux-scsi@vger.kernel.org mailing list.

Kurt, Guennadi:  Is there a current patch posted somewhere?

tmscsim driver should be used in 2.6. I've posted the "final" version of a
patch to this driver on linux-scsi. Kurt wanted to put it on his site for
download, so, maybe it's there. Otherwise have a look in linux-scsi
archives. It should be included in 2.6 at some point, possibly, 2.6.1...

P.S. heh, this is becomming a FAQ:-)) Looks like there are a couple more
users of this driver / chip then I initially thought:-)

Hey, how about us advansis users?  There is at least one, me...  And 
thats the only driver in the whole compile that spits out visible 
warnings about check_region() being deprecated.  But its still 
working, so far.  I presume it will until such time as check_region() 
is actually removed from wherever it lives.

Well, wouldn't it suffice just to remove the deprecated checks? The only
(for recent kernels) request_region() does check the return code. So, this
should do:
