I looked into that a year or two back and came to the same conclusion.
It probably woldn't be hard to port eCos to one of the boards that is
supported by Qemu, but I didn't see much point in that when it runs on
the 386 Qemu target.

There are patches for Qemu that allow you to run eCos for Atmel
AT91SAM9263 on Qemu:

I've never tried it with Grub2.

I've never heard anything good about Grub2.  It's reported to be huge,
bloated, and difficult to install and use. I did install it once on a
Mac Mini, and it's not someting I'm looking forward to ever using.

I have tried running eCos programs build for floppy startup, but I've
never been able to get that to work.
