How to set 1280 800 (widescreen) resolution in RHE Linux 4?

The problem is simple. I have installed Red Hat Enterprise Linux 4 in VMWare Workstation(though I suppose that shouldn't matter, but am not sure) and I want to set its resolution to 1280 x 800, (which is my widescreen laptop resolution). But I couldn't find any solution to this. All the monitors which I selected in the Applications-->System Settings-->Display, had either 800x600, 1024x768, or 1280 x 960 but didn't have a 1280x800 resolution. I tried a few things found on the internet like modifying the file /etc/X11/xorg.conf and replacing all the occurrences of 1024x768 by 1280x800, but with no success... it doesn't show up in the list when I select from the Display.

Any ideas? I know it can be done.
Thanks !

First thing, did you install the VmWare Tools, and what version of VmWare workstation are you using?

You might want to update to the newest version, I think 6.5?If you can't upgrade due to licensing (I don't know how licensing for the paid versions of VmWare work), try using VmWare Server 2 instead, which is free.

I don't think that would solve the problem. The culprit is linux, not VMWare.
Anyway, I found out the solution to the problem myself, which I'm writing for any people who come here searching:

We knew that we have to somehow edit the xorg.conf file kept at path /etc/X11/xorg.conf, but
the initial replacements I had done were not helping. The solution is to do something like tihs:

Replace "HorizSync 31.5 - 48.5" by HorizSync 30.0 - 82.0
make maxlimit of VertRefresh to 90.0
comment the option dpms line by adding a #
#Option DPMS
Add this line just after this:
ModeLine 1280×8003 80.58 1280 1344 1480 1680 800 801 804 827 -HSync -VSync

And then add a "1280x800" in each SubSection "Display" Modes. (Initially I was only doing this)

(Some of the changes done might be highly irrelevant, but this worked for me so I'm writing here. I'm not a linux or hardware expert) Some more knowledgeable people can comment on this.
