> o i845G fixes
I just tried 2.4.20-pre6 on my Intel 845GBVL board (845G chipset).
For the first time DMA is available with the DVD drive,
without a -ac patch. But UDMA(25) as opposed to UDMA(33)
with 2.4.20pre5-ac1.Also I got some junk characters in 2.4.20pre6
when it was probing for IDE devices:
*****DMESG 2.4.20pre6 snip of the Intel board *****
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx

PCI: Device 00:1f.1 not available because of resource collisions
PCI: Found IRQ 5 for device 00:1f.1

***********
2.4.20-pre6 came up fine with my Gigabyte 845IGX (845G chipset)
equipped machine. (Award BIOS as opposed to Intel's). DMA
started to work with 2.4.20-pre5 on this board. The
latest -ac patches do not work on this machine.
Here are full links to the Intel 845GBVL dmesg and lspci:

Thanks! If anyone needs more info, let me know.
