Compatible with QNX4.25?

We are going to purchase IBM Thinkpad A31 model no 2652K3A laptop with ATI
Mobility RADEON 7500 display chipset and Intel 82562ET network chipset. We
will install QNX 4.25 on it. ATI Rage II and Intel 82557are supported and
we are already using them with QNX4.25 on desktop computers. We just want to
confirm that will these chipsets will equally work fine with QNX 4.25? We
have checked the QNX site for supported hardware.
Pl help us.
