PCI-to-PCMCIA/CardBus, Hardhat Linux 2.4.2, and the 405GP

I am attempting to get a SanDisk or IBM MicroDrive CardFlash interface
device working with a Walnut (IBM 405GP Rev. D) platforms and am using
MontaVista's 2.4.2-mvista_010329 Linux kernel to do so. The PCI-to-CardBus
adapter is a TI1420.

Are there any tricks or pitfalls to get this working? I haven't been too
wildly successful yet using either compiled in or module-based drivers.

Also, the PCMCIA-HOWTO seems fairly explicit that a PCMCIA IDE/ATA drive
such as the IBM MicroDrive or SanDisk cannot be used as a boot device (but
can be used as a root device w/ initrd). Has anyone out there done
otherwise (i.e. built-in drivers, no initrd, w/ a simple root=/dev/hda)?

ANY insight would be greatly appreciated.
