[debian-devel:11528] Bug#57129: kernel-image-2.2.14-compact: [PATCH] Please include vga16fb and diable it by default.
Package: kernel-image-2.2.14-compact
Version: 2.2.14-1
Severity: normal
I don't know if this is fit to compact flavor, but I wish if it were.
Please consider to include the following patch from Hatta. This is required
to build the boot-floppies with the support for Japanese characters.
# Hatta is one of our long waiting applicants. He has been waiting for
# about one year after sending his first mail.
We require the kernel with vga16fb to display Japanese (and maybe KR or GB)
characters on vfb console. Hatta posted the patch to include vga16fb and
to disable that feature unless kernel option is specified.
Can you check if you can include that patch to your package of kernel-image-compact ?
# I add "X-Debbugs-CC" to debian-boot list as well as Hatta and devel@JP,
# becase they are all related to this.
