Eliminate UltraATA/133 support for HPT374 -- the chip isn't capable of this mode according to the manual, and doesn't even seem to tolerate 66 MHz DPLL clock...

argh. Please just delete this version numbering. It's a sure-fire way of maximising patch conflicts.
It's 1.10 in Bart's tree.
Of course, this patch is a fix and Bart's tree also has a cleanup waiting for the merge window -- and I've recast that cleanup already. :-)

The code in Bart's tree has
static struct hpt_info hpt374 __devinitdata = { .chip_type = HPT374, .max_ultra = HPT374_ALLOW_ATA133_6 ? 6 : 5, .dpll_clk = 48, .settings = hpt37x_settings };
I can handle the renaming, but note that Bart's tree has different values as well.
I don't think you need to bother yet. I hope Bart will merge it himself closer to weekend.
