yes, this works (in /boot/loader.conf). 

(though at first sight I completely ignore why, since the panic
 seems to be in sscanf() of a line in  /boot/loader.conf or
 /boot/device.hints starting with "hint." and I certainly did
 not have any "hint.apic.*" line in it )

That said, it now panics a bit further (the 'xdr'-bug I vaguely
remember from recent days? ) :
