I noticed also with libguestfs that boot times have spiralled out of
control again, and it seems to be down to the SeaBIOS change. SeaBIOS
accounts for _9_ seconds of the boot sequence, up from very small
(fraction of a second) for the old Bochs BIOS[1].
rm -rf /usr/share/gpxe directory reduces the SeaBIOS share of the boot
time down to about 5 seconds, but that's still a huge regression
compared to the old Bochs BIOS.
Sounds like you're using a distro and that the distro has improperly
built the GPXE binaries. We don't look for roms in /usr/share/gpxe in
upstream...
For the ROMs we ship, we set BANNER_TIMEOUT=0.
You should file a bug against your distro and try to reproduce with an
upstream build. SeaBIOS takes no time at all with upstream.

I'm sure it's waiting for a keypress or something stupid like that.
It'd be nice if the BIOS could be configured in a "just boot, dammit"
mode where it avoids all interaction with keyboards, network cards,
option ROMs etc.

[1] Once I'd put a patch into Bochs BIOS to disable a 3 second
keypress wait.
