Please check, if this bug still occurs with our new d-i images. Two links for your convenience: Netinst CD image here: http://gluck.debian.org/cdimage/testing/netinst/i386/ Floppy images here: http://people.debian.org/~sjogren/d-i/images/daily/ (you need floppy-image.img and one of net_drivers or cd_drivers)
