and i can only get the 3.2.0 drivers 2 work once i have used the fglrx-glc22-4.2.0-2.5.1.i586-kt400agp3.patch. Getting peeved off with ATI now i am seriously thinking about putting my gf4 440mx back in, not that i want 2. I suspect its something 2 do with this again agpgart: Detected a Via Apollo KT400 chipset in AGP v2 compat mode at 00:00.0, as my mobo wont let me change my agp from x8 and i can't change aperture size either, oh and my mobo is agp v3 not 2 as it states there, and Asus say i need a new bios and when 1 is available they will mail me

I will not hold my breath
