Installation
I chose to reformat and install fresh as opposed to upgrading the 7.1 install because I wanted to make sure that there weren't any odd artifacts left behind.
I used the expert installation mode.  The docs seem to imply that the loader (GRUB or LILO) may be configured to be installed in a partition instead of the MBR for all modes, but I didn't  test this.  If anyone does test this, please let me know what happens.
I used both fdisk and diskdruid for repartitioning.  RedHat 7.2 wants larger boot and swap partitions.  Disk Druid is pretty and all, but a little weak.  Although there is the option of forcing a partition to be primary, there is NOT an option to force a logical partition.  I ended up creating my partition table with fdisk and then going through again with Disk Druid to assign everything.
I stayed with ext2 instead of opting for the new ext3 format.  There is an ext2 driver for Windows that I want to try.
I installed everything in /
Although this isn't the best practice, it will hopefully prevent me from running out of space in a particular "slice".  
This is my laptop workstation, not a server :)
X installed without a hitch.  Fn-F7 switches between external, internal, and both displays.
Audio seems to work just fine with the supplied drivers.
dosfstools
For some unknown reason, RedHat decided to ship version 7.2 with dosfstools-2.7-1.  This version complains if there is a FAT32 partition defined in your mount table!  During boot up, press ^C to get past the whining, otherwise the system won't boot.
Install the version that came with 7.1 or get it from RedHat at www.redhat.com/swr/dosfstools-2.2-8.i386.html.  I had to remove the old version first and disable the dependency checking.  See Bugzilla Bug 55001.
APM
The default configuration wasn't very useful.  Instead of suspending, the system would go into standby mode -- which seems to be turning the screen off.
To Do
DVDs.  Since this is a dual-boot system, playing DVDs in Linux still hasn't been a priority.
Modem.  Still don't use dialup much so this hasn't been an issue for me.
Get a bigger hard drive :(  This is becoming more of an issue.
Mysteries
Is there a SpeedStep utility in the works somewhere?
Can the external display be ran at a resolution higher than 1024x768?
Why can't the firewall administration tool read the installed ipchains configuration file?
Things that could be better
Warm booting from Linux to Win2K does not work well.  I'd guess that some PNP settings conflict.
