Well, I might be of a little help.  I've gotten FC5 working finally on
my D820 dell.

For the audio, I had to get the alsa-driver and follow the instructions
from:
http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Intel&card=ICH+southbridge+HD-audio+and+modem.&chip=ICH6%2C+ICH6M%2C+ICH7%2C+ESB2&module=hda-intel

Then the sound started to work.

My /etc/modprobe.conf as the following:

alias char-major-116 snd
alias snd-card-0 snd-hda-intel
# module options should go here
options snd-card-0 index=0 model=laptop-eapd
options snd-hda-intel index=0 model=laptop-eapd position_fix=1
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# bpm
install snd-card-0 /sbin/modprobe --ignore-install snd-card-0 &&
{ /usr/sbin/alsactl restore >/dev/null 2>&1 || :; }
remove snd-card-0 { /usr/sbin/alsactl store >/dev/null 2>&1
|| :; }; /sbin/modprobe -r --ignore-remove

remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1
|| : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel


(NOTE The install, remove lines are each one line)

For the dvd to work correctly, I had to do the following (I have a
different brand, but had the same symptoms)

Add to the /boot/grub/menu.lst kernel line the following:
 combined_mode=libata atapi_enabled=1

This makes the ide be in scsi emulation.  The drive becomes /dev/sdc0
but the links are made correcly:
[bpm]$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 4 May 17 13:06 /dev/cdrom -> scd0
[bpm]$ ls -l /dev/dvd
lrwxrwxrwx 1 root root 4 May 17 13:06 /dev/dvd -> scd0
