I've tested
2.6.27-14, 2.6.29-rc4 (git-5, git-7), 2.6.29-rc5

all of them fails to s2disk with nvidiafb.

dmesg | grep buf
[    1.651258] Console: switching to colour frame buffer device 160x50
[    1.652466] nvidiafb: PCI nVidia NV1d framebuffer (64MB @ 0xC0000000)
[    1.652846] vesafb: framebuffer at 0xc0000000, mapped to 0xfd980000, using
6144k, total 131072k
[    1.653320] fb1: VESA VGA frame buffer device


s2disk works ok with:
dmesg | grep buf
[    0.802424] vesafb: framebuffer at 0xc0000000, mapped to 0xf8080000, using
6144k, total 131072k
