Unless it's on a simulator like SimNow! where the flash chip may be

I've only got some experience with VMware Workstation and not much
else with others, but how should a FlashROM that's being run in an
emulator react?
Like it already does.
Current behaviour is choking on chipset detection and bailing out if I
remember correctly.
I was under the assumption the goal of Flashrom is to be able to
read/erase/write firmware whenever possible.
On real machines the method is dealing with finding chipsets and eeproms.
On virtual machines this method will fail, as will the goals of
writing and erasing. However the goal of reading should still be
possible, even though I admit there's little merit to it.
I think current qemu emulates a flash chip on x86. We should check if
flashrom detects anything. That said, for virtual hardware it should be
possible to check which flash chips are probed by flashrom, then select
one which is big enough for the BIOS of the virtual machine, and then
read the BIOS with
flashrom -f -r foo.bin -c whateverchip
