Yes, and on embedded SoC devices we have watchdog facilities sitting
on an internal chip bus. It would be nice to find access points in
a uniform place on any Linux system. i.e. PCI watchdog on my x86 desktop
is in the same place as the on-chip watchdog on my PPC44x system.

IMHO, anything else would be a logical step backwards from accessing
/dev/watchdog across platforms.
