A decent UPS can help here.

If the disk is dead then the BIOS will skip it and the system should
boot normally (I've tested this by pulling a disk since I didn't have
a suitable dead disk to hand).  A hard error in the 2nd stage boot
loader, ficl or the kernel is definitely the worst case - I agree that
this is very difficult for software raid to recover from.

Note that even with hardware raid, there are still lots of failure
points.  The least reliable parts of a current computer are the CPU
and PSU fans, not the disks.
