[Eee Pad Transformer Android Development] Gatak:
Hm. Odd. On my Gentoo Linux machine I have in /sys/block/zram0:

zram0 # ls -lF

And on my Galaxy Spica (tom3q's CM7.2 rom) with zRam enabled I have:

-r--r--r-- 1 root root 4096 Apr 17 19:43 alignment_offset

What dmesg output do you get when you do "modprobe zram" ? You could try 'echo "1">reset'

I think that the dev device should have been made. Perhaps under /dev/something/zram0 ?

zram0 # cat dev
252:0

zram0 # ls -lF /dev/ |grep 252
