The priority, as I understand it, is driven by the
highest vector
number.
Actually, lower vector numbers have higher priorities. The priority
level is determined by the upper four bits of the vector number. Unfortunately I
know of no method to tune the system interrupt
priorities other than move cards ...
The kernel must be configured to assign different vector numbers to
specific interrupts. The standard kernel cannot do this, but, as it
happens, I've just written a patch which adds this capability. See
