Problems installing/upgrading to 6.06 and 6.10

Hi, I am quite new to ubuntu and I have troubles installing 6.06 and 6.10.

I have tried to install both ubuntu 6.06 and ubuntu 6.10 from alternate i386 CDs and desktop i386 CDs.

With desktop CDs I can't even get to install ubuntu. The system just freezes.

With alternate CDs either of them (6.06 nor 6.10) could not detect my hardware: network device and hard drives. I get a list of hard drive drivers, but none of them works. I have three SATAII hard drives in my PC and windows xp installed to one of them and the meaning is to get ubuntu to work on one of them.

I got 5.10 installed without problems (the installer detects my hardware) and it works ok, so I tried upgrading 5.10 to 6.06 using guides found from the ubuntuforums. The upgrading seems to go without problems, but when I restart and try to boot the newly installed kernel 2.6.15-27-386 I get error messages and I can't get any further.

PCI: Error while updating region 0000:00:06.0/4
PCI: Failed to allocate I/O resources...
PCI: Failed to allocate mem resources...
...
and finally I get the line
/bin/sh: can't access tty; job control turned off

As far as I understand the problem is recognizing my hardware.

I can boot the older kernel in the GRUB list. I tracked 0000:00:06 from the device manager in ubuntu and it points to CK804.

I have Asus K8N4-E Deluxe motherboard and I have Sempron 3100+ processor (32-bit).
My video card is Sapphire RADEON X700 PRO and to get the Xserver work I have to use fglrx.

I'd appreciate if someone could help me out and point me to right direction. Thanks
