I saw this once when using 2.6.6, it was messing up the filesystem 
structures as well (ext2 & ext3), replacing mostly with nulls, some 
with random letters and numbers, for 4-6 character lengths, and not on 
any nice boundaries.  Since I stopped trying to use the ATI framebuffer 
driver (this is on a 21164A alpha, 164LX motherboard, ATI Mach64 CT 
video), it seems to have stopped.  Also, I noticed that the framebuffer 
driver didn't work so well.

2.6.7-rc1 seems to have a compile error for alpha as well, I'll post 
that in a separate email.
