it's virtualbox that was no longer running ok :-(, so after spending
time compiling qt4, I managed to compile vbox so now I have:
	3.1.6_OSEr59338

I'm running vanilla pxeboot, my etherboot rom is not mine, I just compiled it
under linux (under freebsd it was imposible to compile).
Since the server is diskless, but has a few nics, I'm using a spare one for
vbox.

BTW, the 'sometime works' is now 'sometimes failes'! before, after the first 
reboot,
the kernel would panic, the next reboot would hang. Now, reboot mostly 
succeeds :-)

attaching a console boot, 
HTH,

I'm attaching the boot console output.
