VGAROMs on MXM graphics cards need certain int15h functions present
to function properly.
On HP EliteBook 8560w with coreboot and Quadro 2000M, this warning
is displayed for 30 seconds, making every boot extremely slow:
ERROR: Valid MXM Structure not found
POST halted for 30 seconds, P-st

ATI, AMD, and Nvidia based MXM cards exist. I don't know of a way to
probe it to find out if it's an MXM format card. And

Do you mean, run mxm30_setup unconditionally?
And it checks if the file exists:
else if (mxm30_setup(pci))
/* nothing left to do here */

Thanks!
