I installed latest 
xserver-xorg-video-geode_2.11.0-0.3_i386.deb
from:
http://lunge.mit.edu/~dilinger/debxo-0.5/
It got slightly faster, like 10% but the situation is still roughly the same. I don't think it is the JFFS2 as top shows most of the cpu time is spent in the Xorg process. 
A couple of suspicious things:
1, /proc/meminfo shows MemTotal: 221776KB Can someone confirm whether this is normal?
2, Console (without X) is also quite slow. I know fbcon can be slow and unlike x terminal it is synchronous so it has to draw every char literally but still I didn't expect it to be this slow.  
3, every once in a while (10 mins or so) there is a message in console like: 
JFFS2 warning: jffs2_sum_write_sumnode: Not enough space for summary, padsize=-60
4, dmesg is flooded with thing like:
[ 1950.351880] olpc-ec:  received 0xe3
[ 1950.351880] olpc-ec:  received 0xc2
[ 1950.352019] olpc-ec:  running cmd 0x15
[ 1950.353035] olpc-ec:  received 0x41

I could also reflesh debxo0.5 or latest joyride build to try. Is there anyway I can build a set of dat/img files from my current nand so I can come back easily?
