It changed from 1x to whatever was set before (excluding fast writes) by the
BIOS by default, since there were some problems with the old scheme.
Since this works for you with AGP 1x, it indeed looks like AGP 2x doesn't work
stable for your setup. Which is pretty weird, I've never heard of BX chipset
making trouble with AGP 2x (I've certainly used that), nor that 9200 would be
problematic with AGP 2x. (That is, unless you overclock the FSB to 133 on these
boards which will give you 89Mhz AGP instead of 66, or have one of those with a
AGPFS jumper which will give 100Mhz AGP clock at 100Mhz FSB if set wrong). The
only radeons I know of being problematic with AGP are some early radeon 9700
which had problems with some chipsets at AGP 8x speed.
Just to clarify, you have two different rv280-based cards which don't work
stable at AGP 2x but work at AGP 1x in two completely different boards?
