It can be a problem. For ISA bus cards the main board often cannot yank the 
bus reset lines to take the cards down. The latest 2.1.x kernels add
a notifier chain drivers can hook functions onto to be called at reboot
time. This is used to turn the WDT watchdog off so it won't fire by
mistake during a reboot. Its usable for other devices too.
