Hi Ken, I managed to compile linux 2.6.21.5 with some extra patches found on the net [1] and run it on my hx2490b. Unfortunately I had this shifted screen problem... Previous kernels had the same problem and also for some reason failed to support my 2GB SD card on which I hosted the filesystem image file.
In order to compile the kernel you have to prepare a proper toolchain. The one created by cross-tool worked fine for me. Optimization for size didn't work well though. I'm quite new to linux on ARM, but I can devote some time to help. If you need some more detailed info or help please don't hesitate to contact me on priv.
