I had this same problem with my system running 2.6.6 with udev.  As long
as udev was enabled, grub-install or update-grub would resolve the
/dev/hda symlink to /dev/ide/host0/bus0/target0/lun0/disc and complain
that there was no corresponding bios drive.

Yes, I'm able to reproduce this if I delete /boot/grub/device.map

   /etc/fstab - attached
   /boot/grub/menu.lst - attached
   
   $ mount
   rootfs on / type rootfs (rw)
   /dev2/root2 on / type ext3 (rw)
   proc on /proc type proc (rw,nodiratime)
   sysfs on /sys type sysfs (rw)
   /dev2/root2 on /etc/udev/.dev type ext3 (rw)
   none on /dev type tmpfs (rw)
   devpts on /dev/pts type devpts (rw)

   /dev/hda5 on /usr/local/games type ext3 (rw)
   tmpfs on /dev/shm type tmpfs (rw)
   usbfs on /proc/bus/usb type usbfs (rw)
   
   $ ls -ls /dev/hda
      0 lrwxrwxrwx    1 root     root           32 May 26 20:03 /dev/hda

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specifiv kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
# kopt=root=/dev/hda1 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)

## should update-grub create alternative automagic boot options
## e.g. alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(recovery mode) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
