Well, PSN-2007-08-031 is pretty clear about the compact flash requirements:
"Beginning with JUNOS 9.0 (scheduled for release in February, 2008), a 256MB compact flash device is not large enough to support JUNOS software installation on M-Series, T-Series, and TX-matrix routing platforms." That said, you seem to have debunked that idea a little. I'll be running it by my account team, but I'm expecting a 'maybe it will run, but it isn't supported' kind of answer.
