I also have an intel wireless chipset (3945) with wep encryption. Let me know what other information I can provide. As a side note, it would be really nice if there was a reference to the commit or patch that was supposed to address the issue when these bugs are marked resolved. I know it's extra work, but it would make it easier for me to chip in on things like this.
