small report: It's missing larger parts of pmode (that's still "beta"),
and simply replacing their (bochs?) bios with my qemu-tested cbv2 image
results in errors like:

java.lang.IllegalStateException: Unimplemented Microcode: JUMP_FAR_O32
java.lang.IllegalStateException: Unimplemented Microcode: STORE0_CR3
java.lang.IllegalStateException: Unimplemented Microcode: LGDT_O32
@ 0xf536a


java.lang.IllegalStateException: Attempted To Construct Reserved Segment

at least these errors should help filling in the missing bits if someone
is interested.

When that works, we could provide a .jar file with a demo bios image or
something like that, for instant experimentation as java applet.
