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? ) :
