Hmm, probably I didn't understand very well, but I didn't think the
situation was quite as bleak as this...

Didn't Clemens Ladisch write a (now outdated) patch to re-assign
APIC priorities in software, and a program to change PIC interrupt
priorities?

... And isn't part of the point of running the rt kernel patch that
you can give your choice of priorities to the different interrupt
handling threads?

Is the latter an intrinsically inferior solution?

I think his BIOS doesn't give him any control, which is why he was
trying to identify the motherboard, to get a less restrictive BIOS :-)
