the driver currently is set to use INTR_TYPE_MISC, which from my 
understanding can only be masked with splhigh(). using another INTR_TYPE 
may be possible, so this is something i can explore.

however, the device interrupts at a constant 1000Hz, as it's a quad-span 
E1/T1 line card, and thus it needs to have that interrupt serviced pronto 
to avoid E1/T1 frame slips. any advice here ?
