After recompilation with new compiler of wifi driver I got:
wlags49_h1_cs: falsely claims to have parameter channel
wlags49_h1_cs: falsely claims to have parameter channel
wlags49_h1_cs: falsely claims to have parameter channel
wlags49_h1_cs: falsely claims to have parameter channel
The module is ported from Agere sources and is using old style MODULE_PARAM &
Co. The relevant part looks like:
static p_char *network_name = PARM_DEFAULT_SSID;
static p_u8 channel = PARM_DEFAULT_CHANNEL;
static p_u8 distance_between_aps = PARM_DEFAULT_SYSTEM_SCALE;
static p_u8 transmit_rate = PARM_DEFAULT_TX_RATE;
static p_u16 medium_reservation = PARM_DEFAULT_RTS_THRESHOLD;
static p_char *microwave_robustness =
PARM_DEFAULT_MICROWAVE_ROBUSTNESS_STR;
...
MODULE_PARM(network_name, "s");
MODULE_PARM_DESC(network_name, "Network Name (<string>) [ANY]");
MODULE_PARM(channel, "b");
MODULE_PARM_DESC(channel, "Channel (0 - 14) [0]");
MODULE_PARM(distance_between_aps, "b");
MODULE_PARM_DESC(distance_between_aps, "Distance Between APs (1 - 3) [1]");
MODULE_PARM(transmit_rate, "b");
MODULE_PARM_DESC(transmit_rate, "Transmit Rate Control (1 - 7) [3]");
MODULE_PARM(medium_reservation, "h");
MODULE_PARM_DESC(medium_reservation, "Medium Reservation (RTS/CTS Fragment
Length) (256 - 2347) [2347]");
MODULE_PARM(microwave_robustness, "s");
MODULE_PARM_DESC(microwave_robustness, "Microwave Oven Robustness Enabled
(<string> N or Y) [N]");
...
where p_u8 is defined as
include/wireless/wl_internal.h:#define p_u8 __u8
Now, what happens is apparently - only parameters defined as pointer or array
appear in strtab; no parameter of type 'b' is found:

The distribution is Mandriva with gcc-4.1.1-1mdk, stock 2.6.16.18. Full source
of module is available on request if required. This has been compiled before
with gcc-4.0 just fine.

P.S. and yes, I should have fixed obsolete module usage; it is just oo much
work for somehing used privately only :)
