yup, but first id try using root explorer or adb to make a disable_lagfix file and putting it in sdcard/voodoo and rebooting the phone. but make sure you have the voodoo uninstaller on your sdcard already from the above thread.
it can take 5-40 minutes to reboot/disable voodoo, dont batt pull.
if it goes longer than that, pull the batter and power on, it *may* finish unistalling and boot fine.
if that works flash a nonvoodoo kernel, let it boot and then delete the disable_lagfix file, and ur good to go.
