OllyDbg can't load up drivers and monitor them. I'm assuming that ovbiously because of the fact that a usermode application can't read a kernel mode driver.

However, is there any software which can view to any degree another driver and monitor api calls?

Thanks

If it's not a function that runs in a irql level different than passive then you can use cheat engine's kernelmode debugger and enable the global debug function
Then place a breakpoint at the specific address, or setup a luascript that logs all the calls

Tip: If it's an exported api you can use kernel_apiname, else use the driver list and see if you can find the driver and the specific function (or do an aobscan in that region. Make sure kernelmode querrymemoryregions is also enabled)
