[gentoo-user] 回复： [gentoo-user] Can't find driver for VGA in kernel source tree

[Lavender]

I have just tried , the output is like something below

  

 01:00.0 VGA compatible controller:  ATI Technologies Inc M92 LP

 Subsystem: Hewlett-Packard Company Device 3644

 Flags: bus master, fast devsel, latency 0, IRQ 10

 Memory at 80000000 (32bit, prefetchable) [size=256M]

 I/O ports at 3000 [size=256]

 Memory at 90300000 (32bit, non-prefetchable) [size=64K]

 Expansion ROM at 90320000 [disabled] [size=128K]

 How can I find the driver according to these information ?

Have you tried lspci -v which gives verbose information about the 

device, including the modules involved?
