Making a change in /etc/default/grub does not take effect until the actual
Grub menu is rebuilt. It's a config file, not a menu file.

IIRC, I've solved this problem in the distant past by in BIOS setup changing
memory size reserved for video controller from 1M to 8M.

GRUB_GFXMODE=1024x768 assumes you are using Grub2. In Grub legacy what you
need is video=1024x768 or video=1024x768@60 on the kernel cmdline. I have
multiple i945G systems using both vga=1024x768@60 and Grub Legacy, but none
Lenovo.
Which distro are you using?
