Given that the 4G only has two modes, setting either of these = 2
doesn't really make sense.  Set them to 1 and you'll observe the same
results.  If you cat /sys/devices/platform/eeepc/cpufv you should see
that the value 0x201 is reported, indicating that 2 modes are available
and mode 1 is in use.  If you try to set any value higher than 1, an
error is returned:

dove:~# echo 2 >/sys/devices/platform/eeepc/cpufv 
-bash: echo: write error: Invalid argument
dove:~# echo 1 >/sys/devices/platform/eeepc/cpufv 
dove:~# cat /sys/devices/platform/eeepc/cpufv 
0x201
