halo... i had downloaded a driverloader of 16K stack size from the link below:

When i tried to install the package, it was failed and the message shown in terminal as below:

[kokchin@localhost Desktop]$ rpm -Uvh driverloader-2.34_k2.6.5_1.358-1fdr.i686.rpm
warning: driverloader-2.34_k2.6.5_1.358-1fdr.i686.rpm: V3 DSA signature: NOKEY, key ID 5dfbf7dc
