What "running with interrupts" ? :-) Are you talking specifically about suspend/resume ? In this case, normal devices also provide irq_off variants of suspend/resume. In some areas, those semantics are even a problem for sysdevs. For example, it's been a pain in the neck for cpufreq on powermac not to be able to schedule in its suspend routine. Among others...
