I don't think he could be. Doesn't it work only with gfxchips newer than around 
10 years old? His gfxchip looks to me like it could be up to 17 years old:

http://www.dell.com/downloads/ap/topics/servers/1850_specs.pdf says it's an 
embedded chip.

The ati/radeon driver works nicely enough for my rv200 on F25 kernel 4.10.6 and 
server 1.19.2.

I wonder of noapic or nolapic would help?

That bug is about decade newer AMD Island chip(s).

If he has an empty expansion slot, he may need to put a newer video card in it 
order to keep the old server online with Xorg.
