Just having had a look at one of the BIOS flash vendors - there are now devices up to 8Mbit available for both firmware hub and LPC - one vendor in particular has an 8Mbit flash device which attaches directly to LPC.
I have not looked to see which chipset vendors are supporting firmware hub, but according to a bit of documentation I saw, this is aimed at the i8xx chipsets, but it appears as though there is still the 8Mbit barrier.
To be clear the firmware hub is a variant on the LPC bus. And as addresses are clocked across the LPC bus there is no theoretical ROM size limit.
I guess this all depends upon the application - is the application a purely embedded solution with only flash being used, or is it a case of being able to fit a kernel into the BIOS chip - for the latter case, I guess 8Mbit would be adequate.
I suspect Beoboot would be a tight fit, but that is a different problem.
