The atyfb does not work on my 233MHz PowerBook with Mach64 LP, when the kernel is booted from firmware. aty_ld_pll_ct() returns 0x22 and xtal remains at 14.31818. When booted from MacOS, aty_ld_pll_ct() returns 0x3c and xtal is changed to 29.498928. Google indicates that all 4 PowerBook models need the higher value.
