grub 0.97: added config for eee701

I took the default config and changed the following things:
hda1->sda1: eee710 uses the new pata/sata subsystem driver in
  the linux kenrel,and the devices nodes changed from hdxx
  (in use in the old ata subsbsystem) to sdxx (in use in the new
  unified pata/sata one)
ro was temporarly remplaced by rw because of the problem where the boot
  process hung.
  Udev could not write his cache on the disk, should have been fixed
  by commit 2b835db69e6b838fa8628dd85b11b4f930d5f5f9 but it was not
  (same issue than before...maybe this commit fix something else then)
