Subject: libata pata_pdc2027x success on sparc64

Alan & Albert,

I just tried the patch-2.6.17-ide1.gz libata PATA patch
on a sparc64 box in which I had put an Ultra133TX2 PCI
card (pdc20269) and an old 80GB IBM Deskstar disk. The
results were excellent: did lots of I/O with no kernel
errors, and I got about 45MB/s read speed at udma5.

(A minor nit: the patch kit doesn't have a config option
for pata_pdc2027x, so I had to hack one in. See below.)

In contrast, the old IDE pdc202xx_new driver had lots
of problems with CRC errors causing it to disable DMA.
I wasn't able to manually tune it above udma3 without
getting more errors. This isn't sparc64-specific: I've
had similar negative experience with the old IDE Promise
drivers in a PowerMac.
