Not just the second processor as I understand it (also several undocumented components of the SoC) but that seems a fair assumption. The current 2.4 kernel and user apps also mess a little with the MMU to cache/uncache the upper 32MB on demand but nothing to really get in the way. >About bootloader, the same bootloader that boots now could be used >boot armel kernel, don't you think?

(Is that right >or i might be missing some point). I will bow to superior knowledge on that point then. I had in the back of my mind that U-Boot 1.0.0 had a problem with booting ARMEL (some daft ABI assumption) but never took my 2.6 hacks far enough for it to be an issue. My other 2.6 ARMEL projects all use much more recent bootloaders ;). The only other point is you can't boot a kernel of over 680KB (ish, will have to check) from the stock bootloader and it has to be flashed to the NAND. You would need to reflash U-Boot with one of the other variants (Open2x has one) if you wanted to boot the kernel off the SD/SDHC slot. If there is genuine interest in porting the kernel to 2.6 (as a precursor to Debian) then I would be delighted to offer up Open2x's Wiki/Mailing List/SVN etc. to help with the effort (and my time for what little it is worth) but as it stands the small number of hands on the project are focused on our upcoming 2.4 based kernel and firmware release at the moment. Not to say that people would not get stuck in once there was a concrete project underway. Like every other project, all it needs are interested parties with the hardware and the will to make it happen.
