How to use compact flash on embedded 2.6.11 system?

[Dirk Behme]

Hello,

for an embedded system I've written a pcmcia driver very similiar to
drivers/pcmcia/hd64465_ss.c (SS_CAP_STATIC_MAP is set). The system uses 
ARM9 based OMAP device with kernel 2.6.11-rc2. Using this driver with a 
CF card and cardctl I get

# cardctl status
Socket 0:
   no card

- insert a 128MB compact flash card -

# cardctl status
Socket 0:
   5V 16-bit PC Card
   function 0: [ready]
# cardctl info
PRODID_1=""
PRODID_2=""
PRODID_3=""
PRODID_4=""
MANFID=0000,0000
FUNCID=255
# cardctl ident
Socket 0:
   no product info available
# cardctl config
Socket 0:
   Vcc 5.0V  Vpp1 5.0V  Vpp2 5.0V
# dump_cis
Socket 0:
   dev_info
     no_info

Because PCMCIA HOWTO tells that most CF cards lack a CIS, I think this 
is OK (?). Now, I'm not sure how to go on:

Do I need additional userspace tools (except pcmcia-cs-3.2.8)?

How do I 'mount' the card? Which /dev entries are necessary for this 
(major/minor)?

Do I need additional drivers? Kernel patches?

Please see below the output of cardmgr. In kernel 2.6.11-rc2 pcmciamtd 
is marked broken

config MTD_PCMCIA
	tristate "PCMCIA MTD driver"
	depends on MTD && PCMCIA && MTD_COMPLEX_MAPPINGS && BROKEN

and I can't find sram_mtd in 2.6.11-rc2?
