There are people that will tell you 512MB of VRAM isn't enough, but realistically, for today's games, 256MB is sufficient, if you have 1GB of system RAM or more. 512MB is nice, but not necessary for the vast majority of games imo.
If you're willing to turn down/off some of the graphics settings and spend time applying .ini tweaks, as well as run the game @ 800x600, Oblivion will run with playable FPS in most circumstances with most 128MB video cards imo.
Ideally you should have 256MB of graphics memory and an X800 (or Nvidia equivalent) or above graphics card, but you can, supposedly, play Oblivion on a 9500 series ATi card (or Nvidia equivalent) so 128MB should be OK.
Just don't expect to be "blown away" by Oblivion’s realism and graphical beauty, because you wont see any on the older hardware, with consequently lower settings. Heck, my X800Pro @ 550/1120 struggles in Oblivion in some areas in some circumstances and I'm using all the .ini optimisation tweaks I could find and hardly the highest graphics settings...
Oblivion is one of the most demanding games for graphics cards. You have to spend a lot of money if you want a card you can max-out all the graphics settings with whilst having a decent resolution with reasonable FPS...
The short answer is yes, 128MB will be fine, but don't expect high FPS or beautiful graphical scenes, because you wont get them.
