Yep, it would be nice. I will try; but this has to wait a week or more,
end term is approaching and this is a busy period not only for student.
Meanwhile, I tried to compile with PCMCIA debug with nil result (it
seems that a good part of the kernel do not compile if you override
EXTRA_CFLAGS on the make command line). So I tried to define
PCMCIA_DEBUG=4 in the source(s) file affected, but no joy... then I
checked in a clean tree:

cd /linux-2.6.21.3/drivers/pcmcia
% grep PCMCIA_DEBUG *
Kconfig:config PCMCIA_DEBUG
m8xx_pcmcia.c:#ifdef PCMCIA_DEBUG
m8xx_pcmcia.c:static int pc_debug = PCMCIA_DEBUG;
Makefile:ifeq ($(CONFIG_PCMCIA_DEBUG),y)

...so it's seems that only the m8xx modules uses it, and the modules
that load the drivers for my card is yenta_socket... no idea on how to
enable debug.
