I have an epia board which only has one slot. I know from
other people, who have 2 slots, that they solved it like you did.

I think this is an BIOS problem. But I can´t get any officials at epia.
And the BIOS I can download is the one my board uses.
I found some person in newsgroup linux.kernel who had the same problems
with other cards. And someone said this can maybe solved by a kernel patch
that has to be written ;)

I´m watching the thread  but there is no answer about this on 
linux.kernel yet.
Maybe you can post there. Search the subject : PCI problem with RICOH 
RL5C475 PCI/PCMCIA adapter, on 2.4.26
I think the subject they choosed I a little bit misleading. Maybe its 
better to open a new one with
"PCI: Unable to reserve mem region " as subject.
Someone who is responsible for the PCI/BIOS Code can use this is error 
message and post some info/solution for it.
Posting the full error messages and the lspci -vv output from the 
specific card, the used motherboard with BIOS Version
and the kernel version can also help the developer.
