I've never used a fixed-freq monitor in x... I assume you've set the appropriate line in your XF86Config that sets the freq range to 31.5 - 31.5 rather than the default.
Depending on the monitor's control and protection circuitry, it could be fried by sending it signals outside it's range.
From your symptoms, it sounds like your card is okay and your computer thinks X is running just fine, only the monitor doesn't know it...
Good luck with it..
I've had my own trials with display technology recently. All I wanted was big-screen monitor to surf from the couch. (+email +news +quake +synaesthesia). so I threw an ati xpression PC2tv card in a linux box and hooked it to the television. Turns out the PC2tv isn't supported on XFree86, well the monitor output works fine but the s-video output doesn't work. So, I bought one of those external scan converters, but the picture quality looks like crap on my TV and I can't really read anything. So I took that back, ditched my TV, and bought one of those big-assed 33" monitors that will also take TV input from my vcr. this looked good at 800x600. Next, I wanted to surf full-screen (like in IE4.0), which netscape doesn't do to well. So, I decided to use VNC to access my Win95 box and actually USE Internet explorer viewed w/ my linux box. but it was very slow and unstable. So, I upgraded the NICs to 100mB and switched to WinNT and upgraded the Win box from P100 to AMD300. this was stable and runs at an acceptable speed. so now I am surfing full-screen from the couch, showing IE on a linux box with a wireless keyboard. Problem is that VNC is not sending the right shift key to the vnc server and I have to learn to type a different way or ignore capitalization (I am currently doing both). arrrgh.
so, $2k later, I realized I could've gotten the same effect (almost) with one of those $200 webTV boxes. Or, I could've run Winnt directly on the big-screen without VNC because all the apps I wanted for it also run in DOS/Win32 (IE, mutt, slrn, quake, synaesthesia). aaarrgggHH... (but it was a learning experience)
