To get X started I have removed poulsbo modules...

# find / -name '*psb_gfx*' -o -name '*poulsbo*'
...
/lib/modules/3.2.29/kernel/drivers/staging/gma500/psb_gfx.ko
...
/lib/modules/3.2.29/kernel/drivers/gpu/stub/poulsbo.ko
...
# rm /lib/modules/3.2.29/kernel/drivers/staging/gma500/psb_gfx.ko
# rm /lib/modules/3.2.29/kernel/drivers/gpu/stub/poulsbo.ko

...and save back to USB flash drive while rebooting.

After that, Precise Puppy can run X Window System by vesa driver in this book.
