The only problem I can see with this is if one of the more exotic disk 
controller drivers or file systems drivers goes homicidal (diskicidal?). 
Booting multi, you will automount all your big disks and arrays giving the 
drivers the chance to wreak havoc before you can do much about it. This seems 
pretty unlikely on -STABLE though. You're still in trouble though because 
you've probably lost / which probably contains the backup of the old kernel.

In conclusion, its probably best if disk controller drivers and filesystem 
drivers don't have bugs in them.
