Partition type is not updated after formatting. Grub problems

Description of problem:
FC5 fails to boot after flawless install. GRUB is not invoked, as if boot
sector of installation partition contained no boot code.
MBR contains Ranish Partition Manager boot loader
Version-Release number of selected component (if applicable):
Happened on a MSI desktop and Hi Grade Laptop. Seems computer independent.
Steps to Reproduce:
1.create partition of type vfat or old linux 0x81 (with RanishPartMan)
2.install FC5: ask anaconda to format said partition as ext3. Ask anaconda to
install grub in boot sector of said partition.
3.reboot machine: no boot!
MBR with Ranish is read and boot sequence goes on but selected partition
is not bootable (boot goes to second device in BIOS boot list)
Problem solved by manually correcting partition type with fdisk (no
Still no boot. Re-install of grub with GRUB>setup (hd0,0). Some errors,
not fatal, then boots fine!
My guess: anaconda formats the partition correctly and installs the
system. BUT it doesn't set the partition type to what's needed for ext3; maybe
this causes problems to grub. (or maybe anaconda can't install grub in the boot
record of a partition, but that's less likely).

Just more lengthy description (from a posting I made to Fedora Community Portal Forum)
Is this still a problem? I'm told that parted does set the partition type
correctly so if you're still seeing this, anaconda must not be doing the right
thing when calling parted.
