But there's a pretty good chance I'll get to it somewhere in the next few months. Would be awesome to get x86 binaries working on my SheevaPlug. I also think= that ARMv5 is more common in devices such as NAS, where it is more feasibl= e to run an emulator like this. Thanks devs!

I installed arch linux in a virtuabox and created a chroot for it with= mkarchroot. Transferred it to my pogo plug into /i386/ 2. I comiled qemu-i386 static and put it into /i386/usr/bin/ ./configure --static --disable-blobs --disable-system --target-list=3Di38= 6-linux-user make 3. I also compiled linux kernel 2.6.38 with CONFIG_BINFMT_MISC=3Dy and in= stalled it. uname -a Linux Plugbox 2.6.38 #4 PREEMPT Fri Mar 18 22:19:10 CDT 2011 armv5tel Fer= oceon 88FR131 rev 1 (v5l) Marvell SheevaPlug Reference Board GNU/Linux 4.
