Non PAE, and non 64 bit. Shall I reduce the amount of RAM I have? It 
just came into my mind that Xensource has some info about my HW:

"HP ProLiant DL380 G4, 2 x 3.6 GHz XEON, 4 GB RAM. Xen must be given 
option mem=3583M at boot (at least for non-PAE). With 2 QLogic HBAs 
installed there are problems initializing PCI and dom0 crashes, you may 
have to pass Xen the option acpi=off at boot. Fedora Core 5 test 1 and 
SLES 10 BETA 3 have been used for both dom0 and domU."
