Emulating attributes would be great so you can actually navigate bootloader menus.
I took a look a closer look at this. Some things I found:
- it looks like the syslinux menu on recent Fedora versions doesn't work correctly at all in text mode. This can be most easily seen by disabling CONFIG_VGA_VBE on one of the standard qemu seavgabios builds - without vbe syslinux wont go into graphics mode and the same broken text menu is shown. So, this isn't a seavgabios issue but a fedora and/or syslinux issue.
?! I would love more details...
- I took a quick look at what happens with the ati vgabios on my e350m1 if it is forced into a graphics mode (eg, mode 0x12). I see similar results to what I see with coreboot native seavgabios. So, it looks like most of our troubles are with the standard vgabios interface in graphics vs text mode and not something specific to seavgabios.
The non-VESA graphics mode text interface is a bit "special"... and quite frankly broken on a lot of systems. I thought SeaBIOS was doing okay, so there might be a bug here...
