sky2 fails when memory exceeds 2GB on amd64 kernel

Title: signature
Package: linux-image-2.6.32-trunk-amd64
Version: 2.6.32-5

Package: linux-image-2.6.30-2-amd64
Version: 2.6.30-8squeeze1

No matter what brand, size, or speed of ddr2 RAM I try, I cannot successfully boot when the installed memory is greater than 2GB.
The system is an Acer Aspire M1100 with the most recent BIOS.  I have tried with kernels 2.6.32-5 and 2.6.30-8squeeze1.

During the boot sequence, sky2 fails with a 0x2010 pci error; then several programs slowly load until dmsg appears, at which time the screen fills with hexadecimal errors similar to those in this debian bug thread:


Disabling the network interface in the BIOS allows bootup to finish, although some programs fail to load due to the missing network connection.
Decreasing the RAM to 2GB returns booting to normal.

I've seen numerous references to bugs with this network hardware and the amd64 kernel, but none related to adding extra memory.  I am unaware as to how I can capture the errors, since I cannot finish the boot process when the errors happen.
