What about with 14.10?

BTW you gave output from lshw which does not include the device IDs so it's
a little ambiguous. This is why I use lspci. For example, I have:

$ lspci -vvnn| grep -i "vga controller" -A 11

00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core
processor Graphics Controller [8086:0156] (rev 09) (prog-if 00 [VGA
controller])

        Subsystem: Lenovo Device [17aa:3977]

        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B- DisINTx+

        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-

        Latency: 0

        Interrupt: pin A routed to IRQ 43

        Region 0: Memory at c0000000 (64-bit, non-prefetchable) [size=4M]

        Region 2: Memory at b0000000 (64-bit, prefetchable) [size=256M]

        Region 4: I/O ports at 3000 [size=64]

        Expansion ROM at <unassigned> [disabled]

        Capabilities: <access denied>

        Kernel driver in use: i915
In this case 8086 is Intel Coporation. The 0156 is a 3rd Gen Core processor
Graphics Controller or a Ivy Bridge Graphics Controller.

The 03 refers to a Display controller and the 00 after it VGA compatible
controller, by the way. So that's another something you can grep against.

You can look all these things up at http://pciids.sourceforge.net
