The only place to "look for" such capabilities, since the binary driver doesn't expose this to the kernel, is by using the vesa framebuffer driver instead. That doesn't work reliably on all hardware, so is not enabled by default. You can choose to enable it using one of the 'vga=xxx' boot-time options.
