This is with QMGR / NPE / ETH compiled as modules on top of 2.6.22-rc1.

Patches are your latest versions taken from lkml.

The patch I'm using exhibiting the problem:
http://trac.nslu2-linux.org/kernel/browser/trunk/patches/2.6.22/41-ixp4xx-net-fuses.patch

By reverting commit 53b2e01be55f3c140e2704cf8d5f99ddba0ff823 and 45fba0846f5a5a48ed3c394aa4f8ca93699e7655 from linus' tree, the problem is resolved:

Clearly something to do with the changes to CPU detection have stopped the fuse system working but I can't spot the problem, unfortunately.

Hope you can find out what's wrong,
