If you get something working it would be good if you could share the code
(even if it still needs to be tweaked)

IMNSHO the x86-64 mce.c with its error log is a reasonable start. All
the smarts can be in user space and in mcelog.c. DIMM decoding
is a special case though because the information is really useful
to be printed onto the screen for fatal MCEs. So that one is better
in kernel space.
