i installed fglx driver for ATI radeon 9700 video card. this involved recompiling kernel source for 2.6.11.

before eth0 eth1 ra0 detected automatically but now dmesg says it detected eth0 eth1 but ra0 has disappeared! lsmod reveals that agpgart which is video driver is correctly loaded but rt2500 module is not present when i did modinfo. i know that before fglx driver install rt2500 module was loaded now system says it is not present! how do i recover kernel and/or init settings to previous original knoppix?

plz help.
