Sorry guys, I've actually got it wrong. The hardware that I have been
testing on has a different chipset: Intel ICH8, to what I was using
previously with success with 2.6.19 (this was ICH4 based hardware) - so the
driver is actually different now.
Tejun, your patch for 2.6.20 failed with the same errors.
For completeness I have tested the newer ICH8 hardware with everything from
2.6.15 through to 2.6.21.5 using the ata_piix drivers and it (the Compact
Flash) fails in all kernels. Here is the (relevant) dmesg from 2.6.21.5
showing the CF being disabled:
