Then please file a bug report with Debian.

Under that logic we shouldn't even have CPU configurables, since you 
want it to "just work" whatever crap you're running on.  That is EXACTLY 
what CONFIG_X86_GENERIC means, and the fact that any particular 
distribution is broken with respect to not enabling it is a bug in that 
distribution, and not grounds for breaking the upstream kernel.
