Install old kernel without problem ?

[Philippe Couas]

Hi,
 
Currently i have a kernel kernel-2.4.21-15.0.3.EL   
Could i re-install by rpm an old kernel  kernel-2.4.21-15.EL without
problem ?
I need to re-install it because some products like :
DoubleVision from Tridia.com and
Internal Linuxant HSFmodem installed Modem in DELL server don't like
2.4.21-15.0.3

Philippe
