I've now successfully reproduced the issue in the virtual machine. Firstly, at the installer boot menu, choose Expert Mode.
This allows selection of each installer step from a menu and causes debconf to ask many more questions. At "Install the System" choose a "normal" installation and then for "Drivers to include in the initrd:" choose "targeted: only include drivers needed for this system". syslog shows: May 17 22:55:29 base-installer: info: Using kernel 'linux-generic' May 17 22:55:29 base-installer: warning: Failed to get debconf answer 'base-installer/kernel/linux/initrd'.
