Yes, the magic bochs vga lfb @ 0xe0000000 is gone in recent qemu 
(version 0.14 + newer).  The vgabios looks up the framebuffer bar 
address in pci config space instead of depending on the hardcoded address.

And even when combining this with old qemu this is quite unlikely to 
actually cause trouble as the code tries to move the pci bars as high as 
possible.  On a typical qemu configuration the lowest address used is 
0xfc000000.

cheers,
