Redhat 9 graphical installer display screwup

Description of problem:
Redhat 9 (from the ISO) only displays part of the screen on my Dell, which the
probe says has a GeForce 2 MX (generic) and a NEC LCD1830. The bottom half
of the image appears in the top half of my LCD, and the bottom half is blank.
Booting "linux lowres" does display correctly.
We do not support probing LCD sizes, so sometimes it is necessary to override
the defaults using the 'lowres' or 'resolution=<width>x<height>' command line.
These are documented for exactly this case. There are not plans to support
probing LCDs at this time.
It's fine to not probe LCDs. It's not fine to expect expert users to have to
read the paper docs every time they install Redhat -- it's easy to add
information into the 1st stage of booting saying that LCD users should use the
By the way, I did look in the manual, and the troubleshooting guide says nothing
about all LCDs needing lowres. There is also no "What's different about
installing this version of Redhat" section.
I took a survey of my friends in the office, and all of them said they had never
read the installation guide before -- installation always just worked, and they
considered that to be a great feature of Redhat.
