I performed an install, booting from the floppy drive, using the updated boot images. I saw no sign of the graphical installer at all, and no message explaining why.
What type of install were you performing? Only the cdrom and the nfs installations are available in GUI mode. In addition, there are a number of factors which would prevent the GUI installer from running. If there is not enough memory (32M or more), if the VGA Xserver is not able to run on the machine, if there is not a mouse. All of these things will prevent the GUI installer from running, thus throwing you into the TUI installer program. Without more details about your system I really cannot tell you for sure why the X installer did not come up.
