Testbooted 2.6.21-rc1+todays git on a PC with Intel 845 chipset and PATA
HDD. Works fine but I now have these ACPI errors in dmesg, maybe someone
is interested:

It shows UDMA/100 for HDD and UDMA/33 for DVD-ROM. Visual inspection
confirms that this is correct - DVD-ROM has 40-pin cable and HDD has
80-pin one. So at least the result is not wrong.
ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x0001ffa0 irq 14
ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x0001ffa8 irq 15
ata1.00: ATA-5: ST380021A, 3.19, max UDMA/100
ata1.00: configured for UDMA/100
ata2.00: ATAPI, max UDMA/33
ata2.00: configured for UDMA/33
Should the ATAPI line contain UDMA/100 if 40-pin cable is present??

Ok sorry didn't realise this one had a genuine 40pin cable case, forgot
the -mm message about limiting is only in -mm 8(

But should not it do UDMA/66 then?

40-pin cable limits you to UDMA/33.
