Sound, Network and mounting NTFS does not work

[Jojo]

Hello,

i installed "Zephyroth Leopard 10.5.2" after first problems with booting the system now works good.
But i have no Sound and no wired Network:
- Sound driver (ADI1981HD/ATI Technologies Inc SB450 HDA Audio) - not working
- LAN (Broadcom 57xx) - not working

I have also installed on another Partition Tiger 10.4.9 and I use for sound the AzaliaAudio.kext and for LAN the AppleBCM5751Ethernet2.kext and it works.

My question is can i use the .kext from the 10.4.9 System to the 10.5.2 System?
- Is this depending on the Kernel?
- Where i get the 2 driver for 10.5.2 or can i make the driver self?

Next Problem:
My access to the NTFS Volumes does not work anymore, can not be mounted.
I think after i installed NTFS-3G. I deinstalled NTFS-3G but i can't mount anymore NTFS Partitions!
Is it possible to install the old .kext for mount NTFS Volumes? What is the name of .kext for NTFS?

Please Help !
