Secondary video cards need to have code in their ROMs run to reset
them. When an x86 PC boots it only reset the primary video device, the
secondary ones won't work until their ROMs are run.
Another group needing this is laptop suspend/resume. Some cards won't
come back from suspend until their ROM is run to reinitialize them.
A third group is undocumented video hotware where the only way to set
the screen mode is by calling INT10 in the video ROMs. (Intel
i810,830,915 for example).
Small apps are attached to the hotplug events. These apps then use vm86
or emu86 to run the ROMs. emu86 is needed for ia64 or ppc when running
x86 ROMs on them.
