IRQs

Hi,
Quick question. Is it possible to selectively disable interrupts for a given
IRQ in 386 architecture or can one only disable all interrupts. We are
working on a device driver for a rather stupid device. As we are waiting for
a register to clear on the device, it appears the device is interrupting and a
new device command from the interrupt routine is reseting the register.
Unfortunately disabling interrupts on the device also clears the register.
Any suggestions?
