linuxppc_2_4

After I did it, I have the following :

00:0d.0 Bridge: Tundra Semiconductor Corp. CA91C042 [Universe] (rev 01)
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
        Latency: 0 (750ns min)
        Interrupt: pin A routed to IRQ 21
        Region 0: Memory at effef000 (32-bit, non-prefetchable)
[size=4K]
        Region 1: I/O ports at fffe000 [size=4K]

No more module problem ! Thanks a lot...
