@Stskeeps
Yeah so your plan is to boot into Mer^2 on the N900, run any old un-hildonized Linux program and also be able to run and install Fremantle packages side-by-side; rather than the current solution of booting Fremantle and opening a chroot of Debian to run un-hildonized programs. The question is will this method allow you to run any of the closed-source components without modification.

and to summarize...(based on what you are implying)

Pros
* No chroot needed, so no extra over-head and performance loss
* Run gnome/kde/etc. "Desktop" programs AND fremantle programs (no either/or)
* Reverse-engineering all N900 drivers/components not necessary

Cons
* N900 ONLY
* will need a good amount of work to be "flawless"
* as-of-yet unencountered problems will crop up

Or am I completely mistaken??

...Are you able to magically run omap3 binaries on omap2 hardware? o_O
