I think the kernel _does_ manage to extract just the part it wants from
the data, but it expects the data in binary form. Drop the attached
files in /lib/udev/ and /etc/udev/rules.d/51-microcode.rules
respectively. (There's probably a better way to handle this kind of
thing by putting hooks in rather than using a special rule
which overrides it?)

The recent firmware changes haven't modified this. The important change
seems to have been here (in 2006):;a=commitdiff;h=a30a6a2c

[unhandled content-type:application/x-shellscript]# firmware requests for intel-ucode/* are satisfied by microcode_ctl
SUBSYSTEM=="firmware", ENV{FIRMWARE}=="intel-ucode/*", ACTION=="add", RUN=""
