:(

I've had a try with libata and Alan Cox's 2.6.17-ide1 patch (I'd
previously tried this and had issues, which turned out to be a faulty
drive I think). This seems to get better results (sda is the same drive
as was hde earlier):

/dev/sda:
 Timing cached reads:   1084 MB in  2.01 seconds = 540.41 MB/sec
 Timing buffered disk reads:  166 MB in  3.00 seconds =  55.25 MB/sec

I imagine this is due to:

libata version 1.20 loaded.
pata_hpt37x: BIOS has not set timing clocks.
hpt37x: HPT372A: Bus clock 33MHz.
ata1: PATA max UDMA/133 cmd 0xA000 ctl 0xA402 bmdma 0xB000 irq 11
ata2: PATA max UDMA/133 cmd 0xA800 ctl 0xAC02 bmdma 0xB008 irq 11
ata1: dev 0 cfg 49:2f00 82:746b 83:7f01 84:4023 85:7469 86:3c01 87:4023 88:407f
ata1: dev 0 ATA-7, max UDMA/133, 488397168 sectors: LBA48
Find mode for 12 reports C829C62
Find mode for DMA 70 reports 1C81DC62
ata1: dev 0 configured for UDMA/133

ie it's configuring for UDMA/133 as expected.

The hpt366 driver was stable (I copied 100+G of data with cp/rsync and
it was fine); I've only been running this one (marked "Raving Lunatic"
in the Kconfig) for 5 minutes, so I'll see how it goes. I'm happy to try
out anything you might want for the hpt366 driver though.

No, it has it once (unused) - the used instance is check_in_drive_list()

Right, I found this shortly after I sent my first mail, but it's not a
lot different from what I'm running AFAICT (changes from min to min_t
and the removal of the unused check_in_drive_lists).

Yup. It's a Western Digital Caviar SE16. The RocketRaid 1520 card has a
Marvell 88i8030 PATA/SATA bridge on it for each SATA channel.
