I don't believe theres a game yet like MotorStorm,
but look up Colin Mcrae Dirt! That seems like it could be the alternative, and I believe its coming out for the PC.
Looks very promising indeed.
As for the controllers with movement sensors, I don't know. But, Xbox 360 joypads can be loaded onto a PC with a simple driver from Microsoft. I doubt it'd be so simple with a Playstation 3 controller though.
But with Playstation 2 controllers, you can simply use a PS2 to USB adapter.
Sega Rally Revo (Not sure for the PC though) is the Xbox 360's alternative too, to MotorStorm, with cars affecting the dirt on the ground in physics like in the PS3 title.
