it appears that this is a much older regression, from april 2007.

So this is a regression, but not from 2.6.24 (although somehow
it never hit me before). I don't know about the policy of closing
regressions that come from way before the previous kernel version,
if there is any. Then I will let you manage the bugzilla #10117
as you see fit (but I will be "there" to hopefuly test any
proposed patches).

Thanks,
Carlos
