Hi Heming, Sorry for the late response.
The difference in size of the CF card should not make a difference, esp. if you are using a larger card. Expanding the filesystem to make use of the 4GB space should be fairly simple too---a few commands with fdisk which Google would remember better than I do. As for the error, can I recommend that you try to use a SanDisk CF card? There is something about CF card and Grub's boot sector that SanDisk seems to have got right. http://lists.soekris.com/pipermail/soekris-tech/2008-October/015084.html However, I cannot confirm that this is the problem, so just get one and try.
