Jakub, 

A question arise:

	Your modifications is somehow sparc/ppc aware too ?
If i try to recompile you new package will it work on ppc/sparc 
without any other code change ?


Asking because have done self ppc/sparc .rpm-s from fedora src.rpm with few patches and worked ok
but you probably touched the code in some way that other arches have no chance now to build up
or to work with this new stuff.
