Hm, this seems like an epic FAIL.

First of all, the current code still limits it to 896 MiB, so 512 MiB is
not a significant restriction.

Second, this patch only applies if "crashkernel=" is not specified, so
it doesn't even apply to your situation.

Third, if you have to specify "crashkernel=" that means that there is
yet another problem here that should be fixed.
