 The bootable CDs of Knoppix releases 3.4 and 3.6 have boot kernels 2.4.26 and 2.4.27
 These CDs are currently Hostile to winmodem installations for at least 3 reasons.
 1) The kernels were compiled with gcc-2.95.  While there is provided a /usr/bin/gcc-2.95  
 the default ggc found by compilers is set as:      
    /usr/bin/gcc --> /usr/bin/gcc-3.3
 Thus with casual usage of many winmodem driver packages,
 the drivers will be compiled with gcc-3.3 . Such mismatches between
 a kernel and driver can cause a system CRASH. 
 Thus special effort is required to insure that driver compiles utilize the gcc-2.95
 2) Winmodem packages typically try to write drivers to /lib/modules/ 
 and installation files to /usr/sbin/ folders.
 But these folders are positioned on the ReadOnly CD, and the writes will fail;
 3) Since compiled drivers cannot be placed in /lib/modules/, 
 they are not perceived by a dependencies reading:
    depmod -a
 which would enable simple driver loading on demand or with a single:
    modprobe Last_Modem_Driver
 A Bug Report/offer to help Knoppix with these problems has been filed.

If you can provide a download site for th4 2.4.21-xfs kernel-headers
I'll prepare drivers for you.
