Not a stupid question.

'aes' is an alias for multiple modules that implement AES:

$ grep '^alias aes ' /lib/modules/3.0.0-1-amd64/modules.alias
alias aes aes_x86_64
alias aes aesni_intel
alias aes aes_generic
alias aes padlock_aes

modprobe attempts to insert all of these modules, and some of them will
fail because they require specific processors.  But it shouldn't report
an error unless *all* of them fail.  This was the original bug and is
fixed.

But for some reason there is not a single alias for the modules that
implement SHA-1:

$ grep '^alias sha1 ' /lib/modules/3.0.0-1-amd64/modules.alias
alias sha1 sha1_generic

$ grep '^alias sha1-all ' /lib/modules/3.0.0-1-amd64/modules.alias
alias sha1-all padlock_sha

So this is a different bug.

I've unmerged and reopened #568008 which refers to padlock_sha.

Ben.
