This is a headers problem, mainly in 2.6.  2.6 isn't safe out-of-the-box for 
userland consumption.  I've been toying with some 2.6.10 headers from LMO cvs 
on the gentoo side of things, where we have an "appCompat" patch that plugs up 
a alot of the leaky holes in 2.6.x headers, but I still have to analyze the 
patch and add in some mips-specific bits before these headers can be 
considered remotely sane for even testing.

Those running other distros will probably need similar modifications to their 
headers to make them userland-friendly.
