You _need_ KMS, which means you're already in deep crap, as that thing
is anything but complete, performant and stable at this time.   A major
regression for anyone that had extremely stable and "good enough" Radeon
support...

You will have to use either the Debian kernel/kernel sources, or
upstream 2.6.35.11 (or newer).

The X1400 is a PCIe device, isn't it? agpmode shouldn't matter.

FWIW, 2.6.35.11 + Debian Squeeze, KMS enabled, _all power management
disabled_ is stable on a Radeon X300 (T43).   Enable automatic GPU power
management, and you get unknown NMIs when it switches power management
profiles (i.e. the driver is causing the GPU to mess the PCIe bus).
