Using OpenSUSE 11.1 64-bit (Including Xen) with 8GB RAM, Asus M2NPV-VM and Athlon 64-bit proc (3800+ I think).
I have a Sandisk multi-card reader that works great with my 1 & 2GB SD cards but it won’t recognize my 4GB card. The reader uses /dev/sdd(e,f,g) and when I put my 1GB card in the reader it pops up on /dev/sdf1. When I put my 4GB card in (works in my Canon camera), nothing.
I tried the same scenario on a Mac version 10.4.11 with the same results. I haven’t tried it on Windows yet. I don’t have Windows at home. 
Any help will be greatly appreciated.
