Such things as video memory timing and the like are VERY adapter-specific, making it quite unrealistic for the driver to perform adapter initialisation. Thus the driver requires that the adapter be previously initialised or have a BIOS available. This is simply a consequence of ATI's adapter design and there's dick-all the driver can do about it. One could, I suppose, boot with the onboard adapter as primary, save its initialised BIOS somewhere, and have int10 use that copy in the multihead situation. But the code to do that (securely or not) just isn't there. Your options, at this point, are to talk to Dell (dead end), give up on the onboard adapter in multihead, replace your motherboard, or get a system that's not so broken. Or, as I suggested above, atyfb _might_ come in handy for a change.
