Well, this crash (or something such) is easily repeatable if you disable TT 
mode when building and enable CONFIG_STATIC_LINK.

It is related, probably, either to some patches which went in *after* 
2.6.7-1um (at that time, there was still a separate patch to apply on top of 
the corrisponding kernel), or to some problems with the toolchain. I should 
build a 2.6.7-1um kernel with STATIC_LINK to verify that it works (and then 
that we broke it) or that it doesn't (and then it's the toolchain/build env), 
but I keep forgetting to do it.
