Modify the int 1587 handler to check if the POST phase is still running. If it is, use bigreal mode segment limits so that the caller remains in bigreal mode when the 1587 handler completes. This helps with SeaVGABIOS' use of "direct" framebuffer accesses (an option rom may attempt to display text during its option rom execution which can cause SeaVGABIOS to make the int 1587 calls).
FYI, I have committed this patch.
