I heard an amazing data point from a company a few days ago, discussing the linuxbios issue.
They estimate they have lost $30M just this year due to their inability to support linuxbios on their boxes (no, it wasn't IBM, but it could have been). Now for the company in question, this is peanuts -- not even 1/1000 of their gross revenue. But for the salesman for the company in question, this is lost opportunity to make targets. Their salesmen are more than a little unhappy. But the companies persist in saying "there is no market" for LinuxBIOS, the same way they said "there is no market" for Linux, and the same way they said "there is no market" for Unix.
It's always amazing to me that small companies in the US, with so much more to lose, are so much more willing to take on risk than the big companies, who can waste tens of millions in the wink of an eye -- far more than it would cost them to field LinuxBIOS.
