yep, the rtload module has been ditched in favour of the 
realtime-preempt patch (or something like that) in the newer kernels 
(2.6.12 onwards?).

yes, i think so.

another wierd aspect to the later kernels and their modules - when i go 
into /usr/sbin/ntsysv, it lists the 'rtirq' service as not being 
enabled, when it clearly is ... if i enable it, it is disenabled in 
ntsysv upon restart ... inconsequential, but wierd.
