I got someone to go into the BIOS setup (I am debugging this remotely) and
check the IDE/ATA related options. The two relevant options were set
as follows:
ATA/IDE Mode: <Native> [ Choices: Legacy, Native ]
Configure SATA as: <IDE> [ Choices: IDE, RAID, AHCI ]
I had them change the "Configure SATA as" setting from "IDE" to "AHCI"
and then reboot into 2.6.22-rc2. At this point things appear to be much
happier:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
Probing IDE interface ide0...
Probing IDE interface ide1...

Therefore it seems that for whatever reason, the marvell_pata driver will
only find the Marvell PATA IDE controller if the *SATA* mode in the BIOS is
set to "AHCI". It's somewhat counter-intuitive, but since AHCI is the
"correct" setting for SATA performance reasons it's probably not such a bad
thing.
So, thanks for all the suggestions; the problem appears solved.
