I get a couple errors configuring the kernel make with "make xconfig". - When going into the "Console drivers" screen I get the error: syntax error in expression "(null)|16" - When I save the config I get the error: ERROR - Attempting to write value for unconfigured variable (CONFIG_FBCON_MAC). However, it appears to save ok and the compile goes fine.
Seems to work fine in the late 2.2.1-acN series and 2.2.2
