Transparent hugepage support is very interesting at the moment -- especially because both main x86 vendors are beefing up the support for them in their processors. Intel just added real support for 1GiB pages, but AMD takes the jackpot with the DTLB in the upcoming Bulldozer -- 72 L1 entries and 1024 L2 entries, holding any combination of 4kiB, 2MiB or 1GiB pages.
