An even better ixp400 patch was posted by Krzysztof Halasa on lkml in 
May 2007. There was some vivid discussion, but I didn't see any follow 
ups since then.

Speaking of which opens yet another Pandora's box - projects like 
OpenWRT or NSLU2-Linux (which already use Krzysztof's ixp400 patches) 
always patch the kernels quite a bit in order to support all these ARM 
and MIPS devices... Slowly, some of these patches get merged into 
mainline, though, but sometimes, it looks like they might need some help.
