Debian 3.0 on a Dell PowerEdge 600SC

[Andy <list@firman.us>]

I just installed Debian 3.0 stable on a new PowerEdge 600SC.

When I do "lspci" I get the following:

00:00.0 Host bridge: ServerWorks: Unknown device 0017 (rev 32)
00:00.1 Host bridge: ServerWorks: Unknown device 0017
00:02.0 Ethernet controller: Intel Corp.: Unknown device 100e (rev 02)
00:03.0 Ethernet controller: Linksys Network Everywhere Fast Ethernet 10/100 
model NC100 (rev 11)
00:08.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27)
00:0e.0 IDE interface: ServerWorks: Unknown device 0217 (rev a0)
00:0f.0 Host bridge: ServerWorks: Unknown device 0203 (rev a0)
00:0f.1 IDE interface: ServerWorks: Unknown device 0213 (rev a0)
00:0f.2 USB Controller: ServerWorks: Unknown device 0221 (rev 05)
00:0f.3 ISA bridge: ServerWorks: Unknown device 0227

I could not get the onboard ethernet working so I put in the Linksys card.  
The machine seems to be working fine.  In the BIOS there is a maximum UDMA 
Mode where I have a choice of ATA-33, ATA-66, ATA-100, or none.   It is set 
to ATA-33.  Should I be concerned about the "unknown devices"?  

Or will I simply not be able to use UDMA and lose disc performance?

After doing some research, it seems that getting kernel 2.4.20 will take care 
of the onboard gigabit ethernet adapter and the ServerWorks devices.

But kernel-source-2.4.20 is not in stable...it's in testing.

Does that mean I have to upgrade to testing in order to use kernel 2.4.20?

Or can I just edit my sources, pull down kernel-source-2.4.20, and make a
custom kernel?

Thanks,
Andy
