Experience showed that (64bit) raidutils simply seg-fault reliably (at
least on a kernel 2.6.15-1-em64t-p4-smp from Debian-Sarge/Backports from
approx. 2 years ago, raidutils 0.0.4-5).
For sure that's not an excuse for "allowing" the calls in the first
place (and not at least return some appropriate -E value).

ACK.
And the 32bit raidutils work on top of a 64bit kernel so far (at least
the above version in one case).
