I've even further narrowed it down to the presents or lack of '-vga cirrus'. If you add '-vga cirrus' to the above command line, the guest will boot successfully.
Confirmed: Adding -vga cirrus to the command line cures it too.
That's a strange one :-)
vga sticks out a bit because it's one of the few places where we treat device memory as ram as a performance optimization.
The only time vga has been touched in between v0.15 and v1.0 was during the introduction of the memory API.
It's this commit:

seabios: update to master
This looks like the same issue reported at:
http://lists.nongnu.org/archive/html/qemu-devel/2011-10/msg00029.html
The SeaBIOS fix for this was in rel-1.6.3.1 - but that didn't make QEmu 1.0. Does the problem go away if you upgrade to the newer SeaBIOS version?
Yes, SeaBIOS upstream + qemu 1.0 does fix the problem.
