tmscsim driver not included/not recognizing AM53C974 chipset

Description of problem:
On a SCSI-only machine, with onboard AM53C974 SCSI, none of the FC3
boot images recognize the SCSI controller. While the tmscisim driver
is included in the normal kernel install, I cannot tell if the initrd
for the normal boot options omits this driver or if the tmscsim
driver is not being loaded or does not recognize the chipset.
/sbin/lspci output for the device is:
00:04.0 SCSI storage controller: Advanced Micro Devices [AMD] 53c974
[PCscsi] (rev 02)
Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr+ Stepping+ SERR+ FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B- ParErr+ DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR+
Interrupt: pin A routed to IRQ 10
Region 0: I/O ports at ff00 [size=128]
Version-Release number of selected component (if applicable):
Kernel included with rescue CD, bootdisk.img, FC3 CD #1
Steps to Reproduce:
1. Try to boot machine with diskboot.img, rescue CD or CD #1
2. With no SCSI driver, cannot access CD or HD image.
Actual Results: Cannot continue install.
Expected Results: Should find and load tmscsim driver and recognize
CD and HD.
Additional info: Similar to (same as?) bug 123616.
does it work if you boot with 'noprobe', and select it manually ?
(It may be labelled 'dc390t')
the tmscsim driver should be built, and present in the initrd.
I can't find it, or anything else that looks promising, on the list.
Certainly no Tekram, DC390 or tmscsim.
jeremy, is this something missing from anaconda ?
Yeah, wasn't in the kernel when I did a purge of old drivers, hence it
got nuked from the list I include. Added back.
I just tested the Jan 8 development snapshot, and now diskboot.img
locks the machine up (sigh) and the isolinux version still does not
have the tmscsim driver included. Were the changes incorporated into
todays tree should be somewhat better. The kernel module is definitly being
built, so anaconda *should* be picking it up now too.
I tried the January 14th snapshot, and got the following:
Booting from diskboot.img, I get to the SYSLINUX prompt and
get "Could not find kernel image: linux".
Booting from the isolinux directory, I get a kernel panic - "no init
Since the machine I'm using cannot boot from CDROM, I copy the files
onto the HD and use memdisk, called from GRUB, to get the machine
