I don't understand, this was always taken care of. http://openbios.org/viewvc/cpu/x86/pc/olpc/lxmsrs.fth?view=markup&revision=739&root=OpenFirmware has: msr: 0000.1810 fdfff000.fd000111. \ Video (write through), fbsize which is setting the framebuffer as write-combining. (the "write through" comment is incorrect) I don't have current hardware to check if this is the way things are at run-time (maybe something over-writes that register later), but it was all working fine at some point in the past. _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
