[iPAQ] 2 GB SD-card

Hi.

I just bought a 2 GB SD-card to use it on my iPaq, but it is not readable:
when I plug it and try to read it (raw device read using dd), I get:

 first_minor 0x00000000
 /dev/mmc:[mmc_protocol.c:224] mmc_cim_read_write_block failure during cmd 16, error 3 (ERROR_BLOCK_LEN)
end_request: I/O error, dev fe:00 (mmc), sector 0
[mmc_protocol.c:224] mmc_cim_read_write_block failure during cmd 16, error 3 (ERROR_BLOCK_LEN)

and dd dies with an I/O error. Furthermore, /proc/partitions reports 980224.
On the other hand, I can read it with an USB card reader, and the true size
is 1960448.

I am currently using the kernel version 2.4.19-rmk6-pxa1-hh37 from Familiar.
Would upgrading be any use?

Regards,
