Can't say for vmalloc but not sure it will address your issue if you have large iptables rulesets.

Are you doing something like blocking large netranges, eg countries with individual rulesets? Checkout ipset instead which will give you better perfomance, consolidation of rulesets and may well solve your vmalloc problem.
