This is not exclusive to ATI cards, it happens with nVidia cards as well (at least the 7900 series cards).Inventory Icons not showing up in the Inventory when you have a certain ATI Radeon series graphics card. Not a game-breaker but a PITA.
Also, regarding the winches, I remember reading about them too, and it was a warning that ALL the winches in G1 were susceptible to get stuck (i.e. get bugged) seemingly at random and not work at all. Never had that happen to me, though.
