Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)

Ok..I report again the dma error:
b43-phy0 ERROR: Fatal DMA error: 0x00000000, 0x00000800, 0x00000000, 0x00000000, 0x00000000, 0x00000000
b43-phy0 ERROR: This device does not support DMA on your system. Please use PIO instead.
b43-phy0: Controller RESET (DMA error) ...
b43-phy0: Loading firmware version 478.104 (2008-07-01 00:50:23)
b43-phy0: Controller restarted
The expression "It doesn't work" was referred to your suggest to remove b43.conf file..the kernel doesn't auto choose the right mode..

"It doesn't work" is not a proper error description - please post logs
of what's actually happening (i.e. dmesg).
