"VFS: Cannot open root device "hda4" or unknown block(0,0)
Please apend a correct "root=" boot option
kernel panic - not syncing VFS: unable to mount root fs on unknown_block(0,0)"

well..
did you call me? 
already i read your posting in other threads, but i believed that you could do it for yourself. 
anyway, i assume that you are using gentoo-sources-2.6.12-r?
actually, following options are not different with those of 2.6.13.
you can find following options in device drivers->ATA/ATAPI
you can confirm the symbol(i.e. CONFIG_IDE) at it's own help
maybe, you expected that following symbols appeared on the menu,
but it's true.
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDE_PMAC=y
CONFIG_BLK_DEV_IDEDMA_PMAC=y
CONFIG_BLK_DEV_IDE_PMAC_BLINK=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
and next things, you can find in FILE SYSTEMS->Miscellaneous filesystems
CONFIG_HFS_FS=y
CONFIG_HFSPLUS_FS=m

If you're getting /dev/null errors, you haven't mounted /dev in your chroot. Please post the ATA/IDE section of your kernel config so we can look at it.

Warning: unable to open an initial console.
Restarting system.
-----------------------------------------------------------------------
Your system seems to be missing critical device files
in /dev ! Although you may be running udev or devfs,
the root partition is missing these required files !
To rectify this situation, please do the following:
mkdir /mnt/fixit
mount --bind / /mnt/fixit
cp -a /dev/* /mnt/fixit/dev/
umount /mnt/fixit/
rmdir /mnt/fixit
You may refer to these instructions at /etc/issue.....
------------------------------------------------------------------------
tux login: <- can't type here =(
fixed it
