There are two tools very useful to x86-64:

linux32 - a small tool for the 32bit emulation in linux/x86-64. It allows
to execute programs that need an uname -m of i386 with uname emulation.

and

mcelog - Linux x86-64 kernels since 2.6.4 don't print recoverable machine check 
errors to the kernel log anymore. Instead they are saved into a special kernel 
buffer accessible using /dev/mcelog. mcelog reads /dev/mcelog and prints the 
stored machine check records to stdout. Then the stored machine check records 
in the kernel buffer are deleted.
