Hello again folks.

Continuing on this work, i had to consider building 3.4.

3.4 release stable didn't work also builded fine, and all, but have to
consider building other so, i followed this HOWTO[1] and it builded fine
(3.5 from ia64-unstable) , but the "Permission Denied" error changed
somewhat, i'll post it:

Dom0 boots with 2.6.18.8-xen, no apparent errors, but the xend daemon
fails to start. Any pointers would be greatly appreciated.

This is an ia64 build on Debian 5.0.8 'lenny' with GCC 4.1.2
