The IDE interface of the Geode CS5536 companion chip is a completely
different beast.  It's a more or less standard AMD 8111 PCI IDE device
with slightly different timings.  There's a dedicated driver called
pata_cs5536.c (CONFIG_PATA_CS5536).

The driver was developed on a Soekris net5501.  To my knowledge it's
working fine on ALIX boards.  If that's not the case there may be a
problem with the ALIX BIOS VSA PCI config space emulation.  In that case
you can load the driver with msr=1 to force it to program the IDE
function using machine specific registers instead of relying on PCI.

Let me know how it goes.
