Those of you who've picked up Samsung's recently released Galaxy Tab 10.1 may be interested to know there's now a kernel available overclocking its Tegra 2 processor to 1.4GHz. This kernel uses the 18.104.22.168 base, BFQ I/O scheduler, and increases the voltages to supply more power required for the overclock. You'll want to keep in mind this is a preview kernel so use caution when speeding up your Tab 10.1. As always, root is required to flash a custom kernel.
