Snow Leopard 64bit Kexts

[alimo19]

Hi,
I have installed Snow Leopard in my HP Pavilion dv2850ei intel core 2 duo 2 Gb Ram but I need the following 64bit kext. I have tried a handful but most of them cause kernel panic.[url="http://nawcom.com/osx86"]

1. Audio device [0403]: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller [8086:284b] (rev 03)

2. Ethernet controller [0200]: Marvell Technology Group Ltd. 88E8039 PCI-E Fast
Ethernet Controller [11ab:4353] (rev 14)

3. Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g

Thanks
