it's extremly simple! Count the memory chips.

Most 5200 cards have chips on both sides.
This is not 100% accurate, because theoretically, you can have low profile, 128-bit version, where the manufacturer used 32-bit memory chips. But it didn't happened very often. As general rule, it can be used in 95% cases I would say.
From all my 8 FX5200 I own (one Quadro version), all of them apply this rule. 4 chips - 64-bit, 8 chips- 128 bit, so this will be most common rule.
When you buy wide (not lowprofile) version of PCB, just check empty memory chips. If 4 are populated and 8 positions are empty, it will be almost for sure 64-bit version. But again, some manufacturer could use just 4 32-bit memory chips, and make 64MB or 128MB version, while with 8 memory chips populated, he could use 16-bit chips and double the size of memory rather.
Btw, in case everybody is interested, I've made benchmarks in GLQuake, how much difference is in performance between FX5200 64-bit and 128-bit.
Both stock 250/200 mhz (core/mem)
demo3, GLQuake 1024x768x32
FX5200 64-bit - 85 fps
FX5200 128-bit - 139 fps
demo3 GLQuake 1024x768x32 4xAA
FX5200 64-bit - 23 fps
FX5200 128-bit - 44 fps
FX5200 128-bit OC(275/280) - 57.1 fps OC(290/280) - 57.1 fps (raising core didn't help).
(290mhz mem I've got freeze ... I had only 3.6ns Samsung memory)
