Yes, they are x86-based.  Other archs are on my list of things to do. 
If you would like to pick up the ball with these other archs, the
compile tools are at http://developer.osdl.org/cherry/compile/tools/

A lot of these readl/writel warnings HAVE been addressed.  In 2.6.9-rc2,
there were about 3000 of these warnings.  In 2.6.9, there are less than
1900.
