Ok, so i've tested with a bunch of different CF cards and the R2D-1
FPGA seems to support fewer CF models than R2D-PLUS. Here it goes,
just booting - tested with 2.6.24-rc2-git:

Mitsubishi 22.5 MB - R2D-PLUS: bad, R2D-1: bad
Viking 24 MB - R2D-PLUS: ok, R2D-1:ok
SanDisk 128MB - R2D-PLUS: ok, R2D-1: ok
PQI 40x 128MB - R2D-PLUS: ok, R2D-1: bad
SanDisk Ultra II 512 MB - R2D-PLUS: ok, R2D-1: ok
I-O DATA x115 512 MB - R2D-PLUS: ok, R2D-1: ok
IBM Microdrive 1 GB - R2D-PLUS: ok, R2D-1: ok

I'll post a patch that enables polling on R2D-1.
