Its ich_pata_133 - all the newer chips are.

Intel afaik never supported Ultra ATA 133 officially in any of the
mainstream desktop or mobile chipsets.

You're probably right! But, what about Intel's ICH5 and ICH7/7-R (i945, i975)?

see ata_piix.c: line 193ff
	{ 0x8086, 0x24DB, PCI_ANY_ID, PCI_ANY_ID, 0, 0, ich_pata_133 },
[...]
	{ 0x8086, 0x27DF, PCI_ANY_ID, PCI_ANY_ID, 0, 0, ich_pata_133 },

Maybe Alan or someone from Intel can answer that and thus tell us how to
move forward; it would be really nice to get the patch that started this
thread (it got posted by Chuck again today) could go into 2.6.22, but I
assume the time runs away...

On the other hand, we can leave it, because of a "off-by-one error" in ata_piix.c, 
do_pata_set_dmamode, line ~770:
[...]

/me gets confused by that stuff and leaves the answer to that part to
more knowledged people...
