I also have this problem on my Gateway MX6440. I did not have this
problem in 6.10, the card reader worked fine with tifm_sd / tifm_7xx1,
tifm_core (and mmc_core). In order to get it to work with the 6.10 live
cd I simply have to modprobe tifm_sd and it works.
On 7.04 it used to work occasionally. My 7.04 was an upgrade from 6.10
with a working configuration for the sd card reader, to which I had
added tifm_sd, tifm_7xx1, tifm_core to /etc/modules. When the bug
happened, /etc/modules did not have any ti* in it. Occasionally, (maybe
10-20%) if I started the computer up with the card in it or just
inserted the sd card it work work and everything would be fine. The rest
of the time nothing would happen that I could tell from the GUI. I
realized today that my /root (because I didn't make a separate /var when
I installed on my laptop) is full and I am unable to log in to my
system. My /var directory contains aprox 18GB of logs, mainly in
syslog.0 kern.log.0 syslog kern.log messages.0 messages all of which are
1-4.2GB in size. These huge logs were created in past 36-48 hours as my
SO had left the SD in the laptop which was kept running the whole time.
This is an excerpt from /var/log/syslog

I will try the fixes above and report back soon if they help. The major
issue here for me wasn't that it didn't work, but that the logs put my
machine in an unusable state. While its not a difficult fix for me, and
shame on me for not making /var a separate partition. IIRC the installer
doesn't make a separate /var by default, so its possible that this could
happen to other people as well.
